一、口算题
| 14 + 70 = | 27 + 15 = | 77 - 74 = | 45 + 17 = |
| 93 - 65 = | 65 - 60 = | 99 - 86 = | 93 - 48 = |
| 89 - 57 = | 15 + 81 = | 11 + 77 = | 57 + 43 = |
| 13 + 75 = | 90 - 87 = | 100 - 64 = | 59 + 29 = |
二、填括号
| ( ) - 50 = 20 | 14 + ( ) = 39 | 19 + ( ) = 61 | 55 + ( ) = 81 |
| ( ) - 79 = 16 | 60 - ( ) = 57 | 83 - ( ) = 47 | ( ) - 68 = 29 |
| 42 - ( ) = 14 | 67 + ( ) = 71 | 87 - ( ) = 80 | ( ) - 37 = 46 |
三、虫食计算题
四、竖式计算题
| 65 - 16 = | 48 + 44 = | 49 + 42 = | 90 - 82 = |
