一、直接写出得数
| 67 - 62 = | 92 - 77 = | 5 × 3 = | 9 × 7 = | 92 - 47 = | 3 × 6 = |
| 29 + 11 = | 7 × 9 = | 21 + 70 = | 6 ÷ 2 = | 6 × 4 = | 49 ÷ 7 = |
| 8 × 9 = | 38 + 18 = | 6 × 6 = | 13 + 63 = | 6 × 9 = | 2 ÷ 2 = |
| 81 ÷ 9 = | 4 × 3 = | 7 × 5 = | 3 × 8 = | 36 ÷ 6 = | 95 - 24 = |
| 3 × 7 = | 6 × 5 = | 32 + 64 = | 72 ÷ 9 = | 8 × 8 = | 8 ÷ 4 = |
| 9 × 4 = | 74 - 66 = | 4 × 4 = | 9 × 9 = | 5 × 8 = | 56 ÷ 8 = |
| 16 ÷ 2 = | 5 × 5 = | 5 × 6 = | 49 ÷ 7 = | 42 ÷ 6 = | 3 × 9 = |
| 42 ÷ 6 = | 100 - 32 = | 38 + 24 = | 9 × 5 = | 16 ÷ 8 = | 46 + 26 = |
| 3 × 3 = | 4 × 5 = | 70 - 43 = | 69 + 16 = | 9 × 8 = | 65 - 60 = |
| 70 - 22 + 44 = | 18 + 7 ÷ 1 = | 19 + 57 - 26 = | 32 + 6 × 9 = | 9 ÷ 9 + 37 = | 2 × 7 + 35 = |
二、填括号
| ( ) ÷ 9 = 9 | 7 × ( ) = 63 | 31 + ( ) = 77 | ( ) × 1 = 4 |
| 69 - ( ) = 23 | 2 ÷ ( ) = 1 | ( ) - 79 = 13 | ( ) ÷ 6 = 1 |
| ( ) × 9 = 9 | ( ) - 47 = 44 |
三、竖式计算题
| 50 - 29 - 11 = | 71 - 49 - 18 = | 66 + 17 - 33 = | 56 + 17 + 18 = |
| 39 + 37 + 17 = | 84 - 18 - 36 = | 91 - 31 - 43 = | 65 - 29 + 47 = |
