The ATI TEAS 7 math section trips up more nursing school applicants than any other part of the exam. You get 57 minutes to answer 38 scored questions plus 4 unscored field-test items, and there's no full calculator โ just an on-screen 4-function tool for the questions that allow it. That means fraction-to-decimal conversion, ratio setups, and unit math need to feel automatic before you sit down.
This walkthrough breaks down exactly what's on the section, how it's scored, which topics keep coming back, and how to budget your study time. We'll also show you where to find real ati teas math questions and which prep books actually mirror what ATI puts on test day. You'll also see a realistic 6-week study schedule and a printable formula card you can drill from.
If you've been searching for a clear answer to what math is on the teas test, you're in the right place. The short version: arithmetic with fractions, decimals, and percents; basic algebra; ratios and proportions; geometry measurement; and data interpretation. The long version takes a few thousand words because the way ATI mixes those skills matters as much as the topics themselves. Knowing how the testmakers chain two concepts inside one word problem is what separates a 65 from an 82.
By the time you finish this guide you'll know the 38-question split, the timing trap most test-takers fall into around question 25, the calculator rule that costs people 4-6 points, and a 6-week schedule that gets you from rusty to test-ready. We'll also cover what to expect during check-in, how the scoring works, what counts as a competitive score for BSN versus ADN programs, and the retake rules if your first attempt comes up short.
One quick framing note before we dive in: most students who fail the TEAS math section knew the math. They didn't run out of skill โ they ran out of time, or they translated the word problem wrong, or they trusted the on-screen calculator on a problem better solved by hand. So this guide spends as much energy on strategy and pacing as it does on content review. Bookmark the page; come back to the practice link at the end after each study block.
About 18 of the 38 scored questions live here. Expect operations with whole numbers, decimals, fractions, and percents โ and a lot of conversions between the three. You'll see ratio and proportion word problems, one-variable equations, linear inequalities, exponents, scientific notation, and order-of-operations chains. Mixed-number arithmetic is the single most common stumble: practice converting 2 3/8 to 19/8 instantly.
The other ~16 questions cover unit conversions (metric and U.S. customary), perimeter, area, volume, mean, median, mode, range, basic probability, and reading charts, graphs, and tables. Expect at least 3-4 questions where you must extract a number from a bar graph or table and then do a calculation with it. Memorize the standard conversions: 1 inch = 2.54 cm, 1 kg = 2.2 lb, 1 mile = 5,280 ft, 1 L โ 1.06 qt.
57 minutes for 42 questions means ~1:21 each. The four unscored items are randomly mixed in โ you won't know which ones are field-tested, so treat every question like it counts. The section is computer-based for almost every test center; paper TEAS still exists at a handful of schools but is being phased out. Flagging questions for review is allowed; use it for any problem that takes longer than 2 minutes and come back at the end.
You get a math sub-score from 0-100 plus a percentile rank. National average sits near 65. Most ADN programs want 60+, BSN programs 70+, and elite accelerated programs 80+. The math sub-score weighs into your composite score along with reading, science, and English. A weak math score can sink an otherwise strong composite, so this section often decides admissions.
The official ATI TEAS 7 blueprint groups the math section into two named sub-areas, but underneath that umbrella you'll see roughly a dozen recurring topics. Knowing the topic split helps you decide where to spend the next study hour. The biggest payoff areas โ by frequency on real test forms โ are fractions, decimals and percents, ratios and proportions, basic algebra, and unit conversions. Those five buckets account for roughly 60% of your scored questions.
Here's how the topic weighting tends to break down on a typical TEAS 7 form: fractions, decimals, and percent conversions show up in 7-9 questions; ratios, proportions, and rates account for 4-5; one-variable equations and inequalities, 4-5; measurement and unit conversion, 4-6; geometry (area, perimeter, volume), 3-4; statistics (mean, median, mode, range), 2-3; data interpretation from graphs and tables, 4-5; and word problems that mix two or more of the above, 5-7. The mixed word problems are why pure formula memorization isn't enough.
You don't bring your own calculator. ATI provides an on-screen 4-function calculator (+, โ, ร, รท) on items where calculator use is permitted, and that's the only one you get. No square root button, no parentheses, no memory. That changes how you should solve. Practice doing fraction arithmetic by hand, because typing 3/8 + 5/12 into a 4-function calc takes longer than working it on scratch paper. Reserve the calc for ugly decimal multiplication and percent-of-a-number tasks.
Calculator items are flagged on the screen. If a question allows the calculator, a small icon appears in the corner; otherwise you're on scratch paper only. Roughly half the questions allow the on-screen calc. The non-calc items tend to favor mental math with fractions, simple percents (10%, 25%, 50%), or basic algebra you can solve in two steps. Knowing which problems get the tool actually saves time โ you stop second-guessing.
If you've already worked through an ati teas practice test or two, you've noticed how many questions read like miniature stories. A nurse mixes 250 mL of 15% saline with 750 mL of 5% saline โ what's the final concentration? A patient's IV drips 60 mL per hour; how many hours for 1.5 L? These aren't tricks; they're translation drills. The math behind them is basic, but you have to spot the right setup. Underline numbers, circle the unit asked for, and write the equation before computing.
The single biggest leak point in word problems is solving for the wrong variable. A problem will ask for the unit price; you find the total instead. It asks for percent change; you compute the difference and forget the divide-by-old step. Slowing down by 5 seconds to circle the unit asked saves 1-2 wrong answers per section. Practice rewriting each problem in your own words on scratch paper before you compute โ that one habit is worth 3-5 raw points.
Your raw score (questions correct out of 38) gets converted to a percent and a sub-score. ATI reports a composite score, four sub-scores (Reading, Math, Science, English & Language), and a national percentile. There's no penalty for wrong answers, so always guess on any question you can't solve in time. The 4 unscored field-test items don't affect your reported score โ but you won't know which they are, so treat all 42 the same.
What's a competitive math score? Look at the program you're applying to. Public community college ADN programs often accept Math sub-scores from the high 50s up. State BSN programs typically want 70 or higher. Accelerated BSN and top-tier programs frequently set 78-82+ as their math floor. Pull the score reports for your target schools โ most publish median accepted scores. To see where your overall TEAS sits, our ati teas test study guide includes a score-to-program lookup table for the top 200 nursing schools nationwide.
One nuance: the ATI score report also gives you a proficiency level (Developmental, Basic, Proficient, Advanced, Exemplary). Most BSN programs want at least Proficient in math, which roughly corresponds to a 70 sub-score. Aim for Proficient at minimum; shoot for Advanced if your target school is competitive. The proficiency band, not the raw percent, is what some admissions committees focus on first when they screen applications.
ATI does not give you a formula sheet during the math section. Every formula you need has to live in your head. The good news: the list is short and almost all of it is middle-school level. Memorize these cold during your first week of prep and you'll free up working memory on test day to attack the word problem setups, where most points are won or lost.
Geometry formulas to lock in: area of a rectangle (length ร width), area of a triangle (ยฝ ร base ร height), area of a circle (ฯ ร rยฒ), circumference (2 ร ฯ ร r), perimeter of a rectangle (2L + 2W), volume of a rectangular prism (L ร W ร H), volume of a cylinder (ฯ ร rยฒ ร h), and the Pythagorean theorem (aยฒ + bยฒ = cยฒ). Use ฯ โ 3.14 unless the question specifies otherwise. Memorize, don't derive โ derivation eats your time clock.
Stats formulas to memorize: mean = sum รท count; median = middle value when ordered; mode = most frequent value; range = max โ min. Basic probability is favorable outcomes รท total outcomes. The percent change formula is (new โ old) รท old ร 100. For ratios, set up cross-products: a/b = c/d means ad = bc. Our teas exam prep printables include a one-page formula card you can drill from.
Memorize these: 1 inch = 2.54 cm; 1 ft = 12 in; 1 yard = 3 ft; 1 mile = 5,280 ft; 1 lb = 16 oz; 1 kg = 2.2 lb; 1 L = 1,000 mL; 1 L โ 1.06 qt; 1 gallon = 4 qt; 1 cup = 8 fl oz; 1 hour = 60 min; 1 day = 24 hr. The medical conversions also matter for nursing context: 1 tsp = 5 mL, 1 tbsp = 15 mL, 1 oz = 30 mL. ATI loves to put these in dosage-style word problems.
A high-yield drill: write out the entire conversion list from memory three times during week 1, then once per day in week 2. Spaced repetition locks these in. On test day, when you see a question that mixes metric and US units, you should be able to convert without pausing to recall the factor. That 5-second saving per conversion question adds up to 30+ seconds across the section, which is enough to crack one extra word problem.
The single best thing you can do is take a full-length timed math section in week one of prep. Yes, before you've reviewed anything. A baseline diagnostic tells you exactly which topics are rusty and how off your pacing is. Then you build your study schedule around your weak topics, not someone else's. Most students discover their issue isn't algebra โ it's basic fraction arithmetic done too slowly.
From there, the proven cycle is review-drill-test. Spend 30-45 minutes reviewing a topic (watch a video or read a chapter), then 30 minutes doing 15-25 practice problems on that topic, then return to a mixed timed section every Saturday to track pacing. Khan Academy's pre-algebra and basic geometry videos are free and rock-solid for review. ATI's official study manual is the gold standard for question style โ the questions in their book read identically to test-day items. Mometrix's TEAS book and our teas test practice add extra question banks for drilling.
Pace yourself across the full prep window. Cramming 4-5 hours the day before the test does almost nothing because math fluency comes from repetition over weeks, not hours. Two focused 45-minute sessions per day across 6 weeks outperforms one 6-hour session at the end. If you only have 3 weeks before your test date, condense the plan: spend week 1 on diagnostics and weakest area, week 2 on the next two weakest areas, week 3 on full-length timed sections plus targeted review of any miss patterns.
Take a full-length timed math diagnostic. Review whole-number arithmetic, fraction basics, decimal place value. Drill 20 fraction-decimal-percent conversions per day.
Cross-multiplication, unit rates, scale problems. Work 25 ratio word problems. Add a 20-minute timed mini-section at week's end.
One-variable equations, inequalities, exponents, scientific notation. Practice translating English to algebra (15 problems/day). Memorize all geometry formulas.
Unit conversions (metric + US), perimeter, area, volume. Drill nursing-style dosage word problems. Take second full-length math diagnostic.
Mean, median, mode, range, basic probability. Read 20 charts/graphs/tables and compute follow-up stats. Build pacing โ every problem under 1:30.
Two full timed math sections. Review every miss. Lock in the calculator strategy. Day before: light review, sleep 8+ hours, no new material.
After looking at thousands of score reports and post-test debriefs, the same handful of mistakes keep showing up. The first is calculator over-reliance. People assume the on-screen calculator will save them, type every step in, and burn 30-45 extra seconds per question. By question 25 they're 6 minutes behind, panic, and rush the last 13 questions. The fix: use the calculator for ugly multiplication and division only. Do fractions, simple percents, and ratios on scratch paper.
The second mistake is skipping nothing. ATI does not penalize wrong answers, so a blank is always worse than a guess. If a problem stumps you after 90 seconds, eliminate what you can, guess, flag, and move. Coming back at the end with a clear head solves problems you couldn't crack the first time. The third mistake: not memorizing unit conversions. People expect a formula sheet and there isn't one. Spend 15 minutes per day in week 1 just on the conversion list and it pays off for 4-6 points.
The fourth big mistake is ignoring the data section. Math-strong students often nail algebra and geometry then lose 3-4 points on graph reading because they didn't practice it. Charts and tables look easy, but ATI mixes in two-step questions (read the value, then compute the percent change). Drill 10 graph problems per week throughout prep. Our teas math practice test bank tags each question by topic so you can isolate weak areas.
A fifth mistake worth flagging: misreading negative numbers in equations and inequalities. ATI loves to put a negative sign in front of a variable or include a problem where you flip the inequality when multiplying by a negative. People who learned algebra a decade ago often forget the inequality flip rule. Refresh that rule and write it on your scratch paper before the section starts so you don't blank under pressure.
Show up 30 minutes early. Eat a real breakfast with protein and slow carbs. Bring your ID and confirmation email. The math section is timed strictly โ when the clock hits zero, answers are auto-submitted. Pace check: at the 15-minute remaining mark, you should be on question 25 or further. If you're behind, switch to triage mode: skim each remaining question, do the 30-second ones first, guess on anything that looks like a 2-minute setup, flag, return if time.
For each problem, the disciplined sequence is: read the question stem first (what's being asked), then read the problem body, underline the numbers and units, write the setup, compute, double-check units in the answer. Most TEAS math errors come from solving for the wrong thing โ you find x correctly but the question asked for x+5. Slowing down by 5 seconds to circle the unit asked saves you 1-2 wrong answers per section. For a full overview of pacing, eligibility, and what comes next, see our teas exam tips guide.
Two final tactical tips. First, on multiple-choice algebra problems, plugging the answer choices back into the equation is often faster than solving algebraically โ try answer B or C first to anchor. Second, on geometry problems with a figure, sketch the figure on your scratch paper. The screen figures are small and the act of redrawing forces you to label the values, which prevents misreads. These two habits are worth 2-4 points each on a typical form. Build them in during week 3-4 of prep so they feel automatic by test day.
