一、写出得数
| 4 × 9 = | 7 × 7 = | 9 × 3 = | 6 × 6 = | 3 × 5 = | 22 ÷ 8 = |
| 48 + 33 = | 23 ÷ 3 = | 9 × 4 = | 14 ÷ 7 = | 12 ÷ 2 = | 4 × 4 = |
| 7 × 4 = | 43 + 38 = | 35 ÷ 5 = | 4 × 8 = | 82 - 15 = | 16 ÷ 2 = |
| 3 × 3 = | 21 ÷ 6 = | 68 + 15 = | 5 × 5 = | 7 × 3 = | 52 + 29 = |
| 36 + 34 = | 8 × 9 = | 9 × 9 = | 49 + 49 = | 95 - 76 = | 77 ÷ 9 = |
| 64 ÷ 8 = | 83 - 79 = | 14 ÷ 7 = | 2 ÷ 2 = | 3 × 4 = | 70 - 43 = |
| 4 × 6 = | 20 - 12 = | 5 × 7 = | 28 ÷ 7 = | 20 ÷ 4 = | 36 ÷ 4 = |
| 8 × 4 = | 67 - 58 = | 8 × 5 = | 8 × 3 = | 5 × 6 = | 51 - 22 = |
| 56 ÷ 7 = | 56 ÷ 7 = | 6 × 7 = | 49 + 44 = | 63 + 27 - 45 = | 38 + 37 - 38 = |
| 4 × 7 - 21 = | 35 - 3 ÷ 3 = | 34 - 14 ÷ 7 = | 45 + 37 - 75 = | 85 - 57 + 54 = | 3 × 8 - 20 = |
二、填括号
| ( ) × 1 = 1 | ( ) ÷ 2 = 1 | 16 ÷ ( ) = 8 | 8 × ( ) = 24 |
| 64 - ( ) = 43 | 7 × ( ) = 28 | ( ) - 59 = 12 | ( ) - 79 = 16 |
| ( ) ÷ 7 = 8 | 30 + ( ) = 92 |
三、竖式计算题
| 71 - 54 + 58 = | 79 ÷ 9 = | 22 + 39 - 15 = | 25 + 59 - 39 = |
| 59 + 21 - 55 = | 11 ÷ 7 = | 33 - 16 + 25 = | 43 - 29 + 48 = |
