一、口算题
| 89 - 58 = | 45 + 26 = | 58 + 20 = | 56 + 29 = |
| 30 + 38 = | 26 - 14 = | 81 - 78 = | 56 - 25 = |
| 90 - 54 = | 38 + 12 = | 34 + 64 = | 49 - 38 = |
| 96 - 47 = | 90 - 83 = | 79 + 21 = | 11 + 73 = |
二、填括号
| ( ) - 88 = 10 | 36 + ( ) = 64 | 32 + ( ) = 46 | 67 + ( ) = 76 |
| ( ) - 27 = 45 | 74 - ( ) = 40 | ( ) - 79 = 14 | 24 + ( ) = 83 |
| 83 - ( ) = 49 | 82 - ( ) = 57 | ( ) - 14 = 46 | 70 - ( ) = 44 |
三、虫食计算题
四、竖式计算题
| 62 - 57 = | 80 - 51 = | 49 + 23 = | 68 + 24 = |
