一、写出得数
| 8 × 7 = | 4 × 9 = | 4 ÷ 4 = | 9 × 5 = | 30 ÷ 5 = | 100 - 72 = |
| 93 - 85 = | 5 × 5 = | 5 ÷ 4 = | 6 × 9 = | 4 × 6 = | 9 × 6 = |
| 95 - 89 = | 20 ÷ 5 = | 100 - 61 = | 49 + 32 = | 6 × 7 = | 8 × 5 = |
| 7 ÷ 5 = | 6 × 6 = | 69 + 31 = | 3 × 4 = | 4 × 7 = | 8 × 3 = |
| 36 ÷ 9 = | 9 × 4 = | 6 ÷ 3 = | 5 × 8 = | 63 ÷ 9 = | 40 ÷ 8 = |
| 14 ÷ 2 = | 23 ÷ 6 = | 3 × 3 = | 6 × 8 = | 8 × 9 = | 25 + 25 = |
| 7 × 8 = | 65 + 27 = | 42 ÷ 6 = | 6 ÷ 2 = | 24 ÷ 3 = | 47 + 39 = |
| 46 ÷ 9 = | 95 - 67 = | 47 + 44 = | 7 × 3 = | 20 - 11 = | 8 × 4 = |
| 45 ÷ 9 = | 3 × 5 = | 49 + 41 = | 81 - 76 = | 42 - 19 + 19 = | 93 - 28 + 19 = |
| 47 + 3 × 6 = | 3 × 6 + 51 = | 45 ÷ 9 + 45 = | 75 - 12 ÷ 4 = | 36 - 27 + 38 = | 65 + 25 - 65 = |
二、填括号
| 24 ÷ ( ) = 8 | ( ) ÷ 6 = 7 | ( ) × 4 = 4 | ( ) - 13 = 59 |
| ( ) × 8 = 48 | 30 + ( ) = 68 | 35 - ( ) = 12 | ( ) - 79 = 12 |
| ( ) × 5 = 25 | 45 ÷ ( ) = 5 |
三、竖式计算题
| 55 + 37 - 53 = | 79 - 39 - 38 = | 33 ÷ 4 = | 47 ÷ 6 = |
| 56 + 18 - 65 = | 62 - 32 - 20 = | 62 - 39 + 67 = | 81 - 29 - 29 = |
