| 6 = 6 multiply by 2 | 12 = 12 |
| 12 = 2 x 6 multiply by 4 | 48 = 48 |
| (3 + 5) = (1 + 7) divide by 2 | 4 = 4 |
| (3 x 3) = (27 ÷ 3) divide by 9 | 1 = 1 |
| 10 = 10 divide by 2 | 5 = 5 |
| 6 = 2 x 3 multiply by 7 | 42 = 42 |
| 2 nickels = 1 dime multiply by 4 | 40 = 40 |
| 1 dime 2 pennies = 2 nickels 2 pennies multiply by 5 | 60 = 60 |
| 17 -2 = 5 x 3 divide by 5 | 3 = 3 |
| (3 + 1) = (2 x 2) multiply by 5 | 20 = 20 |
| (5 + 7) = (4 x 3) divide by 6 | 2 = 2 |
| 6 x ? = 10 x 3 | 5 because 30 = 30 |
| 18 ÷ 3 = 1 x ? | 6 because 6 = 6 |
| (4 + 5) x 3 = 35 - ? | 8 because 27 = 27 |
| 9 x ? = 6 x 6 | 4 because 36 = 36 |
| 7 x ? = (11 x 5) + 1 | 8 because 56 = 56 |
| 4 x 6 = 12 x ? | 2 because 24 = 24 |
| 8 x 5 = (11 x 3) + ? | 7 because 40 = 40 |
| 6 x ? = (11 x 5) - 1 | 9 because 54 = 54 |
| 100 -10 x 3 = 10 x ? | 7 because 70 = 70 |
