一、直接写出得数
| 5 × 8 = | 5 × 3 = | 70 + 25 = | 9 × 6 = | 14 ÷ 2 = | 3 × 8 = |
| 8 × 4 = | 72 + 20 = | 9 × 7 = | 49 + 22 = | 8 × 3 = | 100 - 46 = |
| 6 × 7 = | 9 ÷ 9 = | 31 + 65 = | 99 - 37 = | 32 ÷ 4 = | 27 ÷ 9 = |
| 72 ÷ 9 = | 80 - 41 = | 4 × 8 = | 56 ÷ 7 = | 95 - 43 = | 56 + 34 = |
| 5 × 5 = | 5 × 7 = | 9 ÷ 9 = | 58 + 35 = | 12 ÷ 3 = | 8 × 7 = |
| 90 - 81 = | 9 × 8 = | 16 ÷ 8 = | 75 - 58 = | 28 ÷ 4 = | 8 × 6 = |
| 64 + 28 = | 8 × 8 = | 4 × 4 = | 62 - 49 = | 3 × 6 = | 3 × 9 = |
| 4 × 5 = | 96 - 90 = | 12 ÷ 4 = | 12 ÷ 2 = | 7 × 7 = | 28 ÷ 7 = |
| 6 × 9 = | 9 × 4 = | 39 + 12 = | 7 × 9 = | 6 × 3 = | 5 × 9 = |
| 62 + 6 × 6 = | 2 × 5 - 10 = | 16 ÷ 2 + 39 = | 68 - 32 ÷ 4 = | 58 + 34 - 89 = | 36 + 15 - 37 = |
二、填括号
| ( ) × 9 = 27 | 6 × ( ) = 36 | 10 + ( ) = 79 | 32 ÷ ( ) = 8 |
| 67 - ( ) = 15 | ( ) ÷ 9 = 1 | 64 ÷ ( ) = 8 | ( ) - 79 = 17 |
| ( ) - 54 = 17 | 5 × ( ) = 5 |
三、竖式计算题
| 86 - 27 + 37 = | 90 - 73 + 66 = | 38 + 14 - 46 = | 50 - 36 + 39 = |
| 80 - 56 - 18 = | 39 + 43 - 16 = | 82 - 56 + 46 = | 55 - 19 + 27 = |
