一、写出得数
| 9300 - 300 = | 400 + 400 = | 2400 - 500 = | 9 ÷ 9 = | 1400 - 1000 = |
| 100 + 4000 = | 91 - 52 = | 7700 - 100 = | 4300 - 300 = | 9 ÷ 9 = |
| 48 ÷ 8 = | 7100 - 200 = | 9 × 6 = | 1200 - 300 = | 49 + 44 = |
| 35 ÷ 5 = | 2300 - 1000 = | 14 ÷ 7 = | 5 × 9 = | 800 + 400 = |
| 4 × 7 = | 400 + 4000 = | 800 + 600 = | 32 ÷ 9 = | 32 ÷ 4 = |
| 200 + 300 = | 6 ÷ 2 = | 83 - 28 = | 7 × 5 = | 33 ÷ 8 = |
| 600 + 300 = | 500 + 200 = | 7 × 7 = | 1000 + 400 = | 5700 - 700 = |
| 9 × 7 = | 100 + 300 = | 100 + 400 = | 7 ÷ 4 = | 8 × 4 = |
| 3 × 5 = | 63 - 49 = | 1400 - 400 = | 48 ÷ 7 = | 4000 + 400 = |
| 600 + 400 = | 3700 - 700 = | 25 ÷ 5 = | 3700 - 3000 = | 600 + 700 = |
| 49 + 33 = | 3100 - 700 = | 97 - 88 = | 7800 - 300 = | 24 + 39 - 15 = |
| 49 + 35 - 58 = | 36 ÷ 4 + 83 = | 3 - 7 ÷ 7 = | 56 + 6 × 6 = | 6 × 3 + 34 = |
二、填括号
| 6 × ( ) = 36 | ( ) ÷ 7 = 1 | 8 ÷ ( ) = 4 | ( ) + 100 = 800 |
| 66 - ( ) = 32 | ( ) - 100 = 9200 | 600 + ( ) = 800 | ( ) - 1000 = 6000 |
| 35 ÷ ( ) = 5 | 30 + ( ) = 56 |
三、竖式计算题，带“※” 要验算
| 930 - 401 + 314 = | ※ 359 - 259 = | 566 + 956 = | 17 ÷ 9 = |
| 730 - 157 = | 65 ÷ 7 = | ※ 729 + 182 = | 699 - 201 + 104 = |
