一、直接写出得数
| 4 × 4 = | 32 ÷ 4 = | 21 ÷ 3 = | 81 ÷ 9 = | 59 - 24 = | 6 × 8 = |
| 16 ÷ 8 = | 58 + 38 = | 3 × 4 = | 5 × 9 = | 9 × 7 = | 9 × 9 = |
| 54 + 46 = | 50 + 34 = | 32 ÷ 4 = | 28 ÷ 4 = | 4 × 8 = | 68 - 59 = |
| 5 × 7 = | 4 ÷ 4 = | 48 + 22 = | 7 × 9 = | 9 × 8 = | 48 + 48 = |
| 8 × 7 = | 8 × 8 = | 4 × 9 = | 6 × 3 = | 6 × 4 = | 5 × 5 = |
| 65 - 63 = | 45 ÷ 9 = | 28 ÷ 4 = | 8 × 4 = | 13 + 62 = | 8 × 5 = |
| 6 × 6 = | 51 + 49 = | 61 - 52 = | 63 ÷ 7 = | 5 × 3 = | 71 - 48 = |
| 24 ÷ 8 = | 83 - 34 = | 53 - 36 = | 8 × 6 = | 8 × 3 = | 9 × 4 = |
| 78 - 77 = | 81 ÷ 9 = | 18 ÷ 3 = | 8 × 9 = | 6 × 5 = | 17 + 50 = |
| 46 - 37 + 37 = | 76 + 40 ÷ 5 = | 62 + 5 × 5 = | 28 + 15 - 18 = | 3 × 9 + 51 = | 72 - 18 ÷ 3 = |
二、填括号
| 5 × ( ) = 25 | 28 ÷ ( ) = 7 | ( ) ÷ 7 = 9 | 9 × ( ) = 72 |
| ( ) ÷ 6 = 2 | ( ) - 48 = 45 | ( ) × 8 = 16 | 11 + ( ) = 22 |
| 97 - ( ) = 25 | ( ) - 79 = 19 |
三、竖式计算题
| 51 + 19 - 27 = | 43 + 49 - 74 = | 76 + 14 - 78 = | 77 - 28 + 27 = |
| 58 + 17 - 27 = | 35 + 39 + 18 = | 53 + 37 - 81 = | 49 + 22 - 38 = |
