一、写出得数
| 18 + 14 = | 5 × 8 = | 4 ÷ 2 = | 42 ÷ 6 = | 5 × 7 = | 53 + 47 = |
| 8 ÷ 2 = | 4 × 4 = | 8 × 7 = | 8 × 9 = | 69 - 57 = | 24 ÷ 3 = |
| 38 + 24 = | 8 ÷ 2 = | 82 - 81 = | 7 × 3 = | 3 × 4 = | 11 + 75 = |
| 5 × 5 = | 27 + 23 = | 24 ÷ 4 = | 4 × 5 = | 6 × 9 = | 14 + 45 = |
| 7 × 9 = | 6 × 6 = | 61 - 44 = | 9 × 5 = | 30 - 11 = | 6 × 4 = |
| 3 × 5 = | 14 ÷ 2 = | 71 - 22 = | 8 × 4 = | 5 × 3 = | 3 × 3 = |
| 35 ÷ 7 = | 6 × 3 = | 19 ÷ 5 = | 55 - 36 = | 48 + 45 = | 7 × 7 = |
| 8 ÷ 8 = | 3 × 7 = | 4 × 6 = | 4 × 7 = | 7 ÷ 5 = | 4 × 3 = |
| 5 × 9 = | 64 ÷ 8 = | 32 - 13 = | 12 ÷ 6 = | 12 ÷ 6 = | 21 ÷ 7 = |
| 47 + 33 - 28 = | 25 + 2 × 7 = | 89 - 8 ÷ 2 = | 72 - 14 + 22 = | 60 + 5 × 5 = | 28 + 6 ÷ 3 = |
二、填括号
| 49 - ( ) = 16 | ( ) × 6 = 30 | 13 + ( ) = 85 | ( ) - 79 = 14 |
| ( ) ÷ 2 = 7 | 7 × ( ) = 14 | ( ) ÷ 2 = 4 | 2 × ( ) = 8 |
| ( ) ÷ 7 = 1 | ( ) - 49 = 18 |
三、竖式计算题
| 19 ÷ 5 = | 66 + 25 - 37 = | 65 - 37 + 16 = | 48 + 26 - 48 = |
| 32 - 13 + 15 = | 96 - 89 + 73 = | 26 ÷ 3 = | 86 - 57 + 21 = |
