一、直接写出得数
| 48 ÷ 8 = | 48 ÷ 8 = | 9 × 5 = | 8 × 9 = | 15 ÷ 3 = | 8 × 6 = |
| 99 - 98 = | 56 ÷ 8 = | 7 × 8 = | 34 + 29 = | 3 × 9 = | 4 × 5 = |
| 9 ÷ 9 = | 97 - 54 = | 70 - 11 = | 58 + 42 = | 13 + 86 = | 32 ÷ 4 = |
| 98 - 39 = | 83 - 56 = | 5 × 4 = | 52 + 39 = | 6 × 8 = | 7 ÷ 7 = |
| 3 × 7 = | 3 × 3 = | 6 × 7 = | 5 × 6 = | 9 × 7 = | 46 + 24 = |
| 48 ÷ 8 = | 4 × 4 = | 4 × 6 = | 8 × 8 = | 4 ÷ 4 = | 9 × 6 = |
| 9 × 4 = | 24 ÷ 8 = | 5 ÷ 5 = | 7 × 9 = | 48 + 46 = | 8 × 5 = |
| 5 × 7 = | 81 - 45 = | 86 - 53 = | 43 + 23 = | 8 × 4 = | 40 ÷ 8 = |
| 26 + 53 = | 3 × 5 = | 93 - 89 = | 7 × 4 = | 8 × 7 = | 24 ÷ 3 = |
| 73 - 9 ÷ 9 = | 87 - 79 + 47 = | 38 + 43 - 67 = | 48 + 45 ÷ 5 = | 4 × 9 - 26 = | 68 + 4 × 5 = |
二、填括号
| 4 × ( ) = 20 | ( ) ÷ 8 = 7 | ( ) × 8 = 16 | 9 × ( ) = 36 |
| ( ) ÷ 8 = 6 | ( ) ÷ 4 = 9 | 39 - ( ) = 11 | 20 + ( ) = 57 |
| ( ) - 79 = 14 | ( ) - 66 = 16 |
三、竖式计算题
| 17 + 68 - 17 = | 28 + 42 - 42 = | 71 - 41 - 21 = | 22 + 49 - 49 = |
| 35 + 15 - 40 = | 42 - 33 + 75 = | 65 + 26 - 39 = | 77 + 13 - 23 = |
