一、写出得数
| 69 + 11 = | 9 × 9 = | 7 × 8 = | 72 ÷ 9 = | 5 × 4 = | 36 ÷ 4 = |
| 59 + 41 = | 7 × 4 = | 58 + 32 = | 4 × 4 = | 21 ÷ 7 = | 24 ÷ 8 = |
| 45 ÷ 5 = | 90 - 82 = | 3 × 5 = | 5 × 3 = | 3 × 6 = | 90 - 44 = |
| 72 ÷ 9 = | 4 × 7 = | 6 × 5 = | 36 ÷ 6 = | 6 × 9 = | 7 ÷ 5 = |
| 5 × 9 = | 30 ÷ 4 = | 9 × 4 = | 3 × 7 = | 2 ÷ 2 = | 4 × 6 = |
| 14 ÷ 2 = | 16 ÷ 7 = | 8 × 3 = | 54 - 47 = | 6 × 7 = | 3 × 3 = |
| 57 ÷ 8 = | 9 × 8 = | 28 + 13 = | 32 - 28 = | 4 × 8 = | 92 - 89 = |
| 32 + 28 = | 78 + 12 = | 3 ÷ 3 = | 4 × 9 = | 80 - 38 = | 7 ÷ 7 = |
| 61 - 12 = | 44 + 38 = | 5 × 5 = | 14 ÷ 7 = | 69 + 11 - 71 = | 15 + 67 - 48 = |
| 90 - 56 ÷ 8 = | 71 - 38 - 15 = | 66 - 7 × 6 = | 81 - 6 ÷ 1 = | 95 - 7 × 8 = | 44 - 25 + 79 = |
二、填括号
| ( ) ÷ 7 = 1 | ( ) × 9 = 27 | 24 ÷ ( ) = 8 | ( ) × 4 = 4 |
| ( ) × 8 = 56 | 27 - ( ) = 12 | ( ) - 37 = 46 | 42 + ( ) = 86 |
| 72 ÷ ( ) = 8 | ( ) - 79 = 17 |
三、竖式计算题
| 62 - 57 + 67 = | 42 - 39 + 88 = | 50 - 44 + 34 = | 37 ÷ 7 = |
| 22 + 49 - 37 = | 24 + 49 - 45 = | 53 - 39 + 28 = | 9 ÷ 4 = |
