一、直接写出得数
| 12 + 34 = | 37 + 27 = | 42 + 31 = | 5 × 5 = | 4 × 3 = | 65 + 28 = |
| 4 × 4 = | 6 × 4 = | 4 × 6 = | 3 × 7 = | 10 ÷ 2 = | 24 ÷ 4 = |
| 9 × 5 = | 37 + 25 = | 12 + 77 = | 9 × 8 = | 63 - 15 = | 7 × 3 = |
| 77 - 36 = | 3 × 6 = | 20 ÷ 5 = | 63 + 37 = | 9 ÷ 9 = | 9 × 3 = |
| 24 ÷ 6 = | 5 × 9 = | 5 × 8 = | 8 × 7 = | 5 × 7 = | 64 ÷ 8 = |
| 89 - 88 = | 10 ÷ 5 = | 30 ÷ 5 = | 3 × 8 = | 72 - 31 = | 7 × 4 = |
| 50 - 13 = | 8 × 3 = | 6 × 6 = | 64 ÷ 8 = | 21 - 14 = | 21 ÷ 3 = |
| 4 × 8 = | 10 ÷ 5 = | 7 ÷ 7 = | 80 - 62 = | 37 + 33 = | 70 - 17 = |
| 8 × 4 = | 5 × 4 = | 3 × 3 = | 25 ÷ 5 = | 4 × 7 = | 5 × 3 = |
| 50 - 18 - 17 = | 6 ÷ 2 + 19 = | 38 - 18 - 18 = | 12 + 7 × 2 = | 35 - 24 ÷ 4 = | 72 - 8 × 7 = |
二、填括号
| 62 + ( ) = 84 | ( ) × 4 = 8 | 89 - ( ) = 56 | ( ) × 7 = 56 |
| ( ) ÷ 5 = 5 | ( ) - 79 = 18 | ( ) ÷ 2 = 5 | ( ) × 2 = 6 |
| 6 ÷ ( ) = 2 | ( ) - 17 = 29 |
三、竖式计算题
| 47 - 19 + 53 = | 92 - 35 + 26 = | 72 - 48 - 19 = | 60 - 14 + 15 = |
| 81 - 72 + 34 = | 31 + 49 - 20 = | 23 - 17 + 25 = | 70 - 41 + 36 = |
