1. Add two-digit numbers

   1. What is 20 + 76?

   Show answer

   Answer: 96

   20 + 70 = 90, and 0 + 6 = 6. So 20 + 76 = 96.

2. Subtract two-digit numbers

   2. What is 98 − 27?

   Show answer

   Answer: 71

   98 − 20 = 78, then − 7 gives 71.

3. Add three-digit numbers

   3. What is 281 + 191?

   Show answer

   Answer: 472

   Hundreds: 200 + 100. Tens and ones: 81 + 91. Total: 472.

4. Times tables to 10 × 10

   4. What is 10 × 6?

   Show answer

   Answer: 60

   6 groups of 10 is 60, so 10 × 6 = 60.

5. Two-digit × one-digit

   5. What is 87 × 6?

   Show answer

   Answer: 522

   80 × 6 = 480 and 7 × 6 = 42. 480 + 42 = 522.

6. Two-digit × two-digit

   6. What is 40 × 12?

   Show answer

   Answer: 480

   40 × 10 = 400 and 40 × 2 = 80. 400 + 80 = 480.

7. Division facts

   7. What is 21 ÷ 3?

   Show answer

   Answer: 7

   3 × 7 = 21, so 21 ÷ 3 = 7.

8. Divide a two-digit number by a one-digit number

   8. What is 88 ÷ 8?

   Show answer

   Answer: 11

   80 ÷ 8 = 10 and 8 ÷ 8 = 1. So 88 ÷ 8 = 11.

9. Equivalent fractions

   9. Fill in the missing number: 4/10 = ?/20

   Show answer

   Answer: 8

   10 × 2 = 20, so multiply the numerator by 2 too: 4 × 2 = 8. 4/10 = 8/20.

10. Add fractions with the same denominator

    10. What is 2/8 + 1/8?

    Show answer

    Answer: 3/8

    The denominators are both 8, so add the numerators: 2 + 1 = 3. The answer is 3/8.

11. Find a fraction of a quantity

    11. What is 3/10 of 100?

    Show answer

    Answer: 30

    100 ÷ 10 = 10, and 10 × 3 = 30.

12. Convert metric units

    12. Convert 73 m to cm. (Just type the number.)

    Show answer

    Answer: 7300

    1 m = 100 cm, so 73 m = 7300 cm.
