一、写出得数
| 18 ÷ 5 = | 100 + 8000 = | 64 + 18 = | 4 × 6 = | 82 - 47 = |
| 9700 - 1000 = | 400 + 300 = | 9 × 4 = | 2400 - 200 = | 49 ÷ 7 = |
| 20 ÷ 4 = | 15 ÷ 3 = | 9 × 6 = | 200 + 900 = | 200 + 300 = |
| 9400 - 9000 = | 300 + 100 = | 83 - 64 = | 90 - 81 = | 8 × 4 = |
| 15 ÷ 5 = | 2700 - 700 = | 18 ÷ 9 = | 78 ÷ 9 = | 300 + 700 = |
| 24 ÷ 8 = | 600 + 700 = | 3300 - 600 = | 1900 - 500 = | 6300 - 700 = |
| 9400 - 400 = | 8600 - 100 = | 25 ÷ 8 = | 4000 + 300 = | 2900 - 700 = |
| 1200 - 800 = | 5 × 8 = | 6 × 3 = | 7 × 5 = | 900 + 600 = |
| 800 + 800 = | 51 ÷ 8 = | 1000 + 800 = | 600 + 100 = | 49 ÷ 7 = |
| 400 + 3000 = | 100 + 800 = | 36 ÷ 9 = | 2300 - 900 = | 7 × 8 = |
| 4500 - 200 = | 73 - 46 = | 78 + 13 = | 2700 - 2000 = | 15 ÷ 5 + 78 = |
| 66 + 72 ÷ 8 = | 79 - 7 × 9 = | 23 + 68 - 81 = | 32 + 8 × 5 = | 95 - 17 - 48 = |
二、填括号
| 15 ÷ ( ) = 3 | 7000 - ( ) = 6300 | ( ) + 600 = 800 | ( ) ÷ 7 = 7 |
| ( ) ÷ 6 = 4 | 95 - ( ) = 32 | 35 + ( ) = 48 | 700 + ( ) = 1000 |
| 8 × ( ) = 40 | ( ) - 400 = 3700 |
三、竖式计算题，带“※” 要验算
| 884 - 563 - 141 = | ※ 215 + 662 = | 312 - 287 = | 477 + 775 = |
| 11 ÷ 7 = | 8 ÷ 7 = | 716 + 283 - 189 = | ※ 215 - 171 = |
