一、直接写出得数
| 30 + 37 = | 68 + 23 = | 41 + 19 = | 9 × 5 = | 12 ÷ 3 = | 6 ÷ 6 = |
| 36 ÷ 6 = | 5 × 9 = | 8 × 7 = | 56 ÷ 8 = | 8 × 9 = | 51 - 16 = |
| 81 - 70 = | 5 × 6 = | 99 - 62 = | 48 + 30 = | 100 - 72 = | 27 ÷ 9 = |
| 6 × 6 = | 8 × 6 = | 7 × 3 = | 4 × 9 = | 9 × 4 = | 3 × 3 = |
| 81 - 44 = | 7 × 8 = | 66 + 34 = | 8 × 4 = | 9 × 6 = | 3 × 8 = |
| 90 - 82 = | 4 × 7 = | 6 × 8 = | 8 × 5 = | 6 × 3 = | 56 + 39 = |
| 84 - 75 = | 63 ÷ 7 = | 8 × 8 = | 7 ÷ 7 = | 3 × 5 = | 4 × 3 = |
| 3 × 9 = | 58 - 20 = | 7 × 4 = | 6 ÷ 6 = | 21 ÷ 3 = | 6 × 7 = |
| 18 ÷ 9 = | 28 ÷ 7 = | 14 ÷ 2 = | 9 ÷ 3 = | 47 + 17 = | 20 + 74 = |
| 79 + 8 ÷ 1 = | 17 + 33 - 49 = | 42 ÷ 7 + 82 = | 6 × 8 - 25 = | 4 × 5 + 68 = | 84 - 17 + 27 = |
二、填括号
| ( ) × 1 = 1 | 8 ÷ ( ) = 4 | 8 × ( ) = 48 | 14 ÷ ( ) = 7 |
| ( ) - 79 = 13 | 89 - ( ) = 30 | 5 × ( ) = 25 | 20 + ( ) = 49 |
| ( ) ÷ 9 = 2 | ( ) - 58 = 36 |
三、竖式计算题
| 56 + 19 - 69 = | 69 + 21 - 68 = | 38 + 39 + 15 = | 60 - 24 + 26 = |
| 18 + 75 - 88 = | 59 + 21 - 13 = | 81 - 54 + 23 = | 73 - 47 + 26 = |
