  1. What is the value of 8 × 7?

    Answer: 56

    This question requires basic multiplication. Multiplying 8 by 7 yields the product of 56. This is a fundamental multiplication fact that should be memorized.

  2. Solve: 45 + 29 = ?

    Answer: 76

    This question requires basic addition. To solve 45 + 29, you add the ones digits (5 + 9 = 14, carrying over 1 to the tens place) and then the tens digits (4 + 2 + 1 = 7). The correct sum is 76.

  3. What is 81 ÷ 9?

    Answer: 9

    This question tests basic division. To find 81 ÷ 9, you determine how many times 9 fits into 81. Since 9 multiplied by 9 equals 81, the quotient is 9.

  4. What is the next number in the pattern: 2, 4, 8, 16, ...?

    Answer: 32

    This question presents a geometric sequence where each number is multiplied by 2 to get the next term. Following the pattern (2x2=4, 4x2=8, 8x2=16), the next number is found by multiplying 16 by 2, which equals 32.

  5. What is 100 minus 37?

    Answer: 63

    This question requires basic subtraction. To calculate 100 minus 37, you subtract 7 from 10 (resulting in 3) and 3 from 9 (resulting in 6, after borrowing from the hundreds place). The correct answer is 63.

  6. Solve: 5 × (3 + 2) = ?

    Answer: 25

    This question tests the order of operations, often remembered by PEMDAS/BODMAS. First, perform the operation inside the parentheses: 3 + 2 = 5. Then, multiply this result by 5: 5 × 5 = 25.

  7. If you buy 3 pencils at $2 each, how much do you spend?

    Answer: $6

    This is a simple word problem involving multiplication. To find the total cost, you multiply the number of pencils (3) by the cost per pencil ($2). Therefore, 3 × $2 = $6.

  8. Which of these is a prime number?

    Answer: 17

    A prime number is a natural number greater than 1 that has no positive divisors other than 1 and itself. Of the given options, 17 is only divisible by 1 and 17, making it a prime number. The other numbers (12, 20, 21) have additional factors.

  9. What is half of 64?

    Answer: 32

    This question asks for half of a number, which means dividing the number by 2. Dividing 64 by 2 yields 32. This is a basic division operation.
