一、写出得数
| 3 × 5 = | 95 - 79 = | 5 × 5 = | 6 × 8 = | 65 ÷ 7 = | 24 ÷ 3 = |
| 48 + 43 = | 6 × 7 = | 10 ÷ 2 = | 53 + 39 = | 60 - 21 = | 8 × 8 = |
| 100 - 51 = | 4 × 6 = | 7 ÷ 7 = | 13 ÷ 6 = | 35 ÷ 9 = | 3 × 4 = |
| 90 - 62 = | 8 × 7 = | 40 - 31 = | 7 ÷ 7 = | 7 × 3 = | 48 ÷ 8 = |
| 36 + 15 = | 12 ÷ 2 = | 5 × 7 = | 4 × 9 = | 3 × 9 = | 70 - 23 = |
| 6 × 9 = | 8 × 4 = | 7 × 4 = | 3 × 7 = | 9 × 6 = | 91 - 63 = |
| 28 + 24 = | 14 ÷ 4 = | 9 × 8 = | 17 + 13 = | 64 + 19 = | 4 × 5 = |
| 5 × 9 = | 4 × 4 = | 8 ÷ 2 = | 36 ÷ 4 = | 48 ÷ 8 = | 24 ÷ 6 = |
| 15 ÷ 5 = | 45 ÷ 5 = | 66 + 34 = | 6 × 6 = | 42 - 19 + 39 = | 86 + 24 ÷ 3 = |
| 49 + 29 - 29 = | 24 ÷ 6 + 16 = | 58 - 39 + 44 = | 67 - 6 × 2 = | 54 - 16 + 34 = | 4 × 9 - 30 = |
二、填括号
| 44 - ( ) = 23 | 6 × ( ) = 48 | ( ) × 4 = 8 | 7 ÷ ( ) = 1 |
| ( ) × 9 = 36 | 15 ÷ ( ) = 3 | ( ) ÷ 5 = 7 | ( ) - 79 = 15 |
| 25 + ( ) = 87 | ( ) - 59 = 19 |
三、竖式计算题
| 58 - 49 + 56 = | 37 + 34 - 57 = | 77 - 18 + 29 = | 64 ÷ 9 = |
| 62 - 14 + 43 = | 10 ÷ 4 = | 31 - 24 + 73 = | 77 + 15 - 18 = |
