一、口算题
| 89 - 47 = | 29 - 18 = | 39 + 23 = | 100 - 11 = |
| 88 - 84 = | 66 - 64 = | 21 + 72 = | 47 + 44 = |
| 19 + 16 = | 83 - 34 = | 69 + 11 = | 30 + 63 = |
| 50 + 48 = | 81 - 73 = | 84 - 79 = | 43 + 34 = |
二、填括号
| ( ) - 21 = 49 | 37 - ( ) = 32 | 82 - ( ) = 79 | 68 + ( ) = 92 |
| ( ) - 79 = 14 | 33 - ( ) = 17 | ( ) - 13 = 55 | 53 - ( ) = 36 |
| 38 + ( ) = 56 | 36 + ( ) = 62 | ( ) - 25 = 18 | 11 + ( ) = 93 |
三、虫食计算题
四、竖式计算题
| 91 - 83 = | 61 - 55 = | 46 + 34 = | 24 + 17 = |
