一、直接写出得数
| 30 × 5 = | 606 × 3 = | 200 × 5 = | 400 × 4 = | 60 × 7 = |
| 600 × 7 = | 70 × 7 = | 7 ÷ 6 = | 50 × 7 = | 2500 - 600 = |
| 92 - 83 = | 905 × 2 = | 305 × 4 = | 900 + 600 = | 6700 - 200 = |
| 30 × 2 = | 90 × 4 = | 12 × 2 = | 100 × 9 = | 550 × 3 = |
| 990 × 2 = | 70 × 6 = | 405 × 3 = | 340 × 4 = | 808 × 2 = |
| 23 ÷ 9 = | 147 - 146 = | 36 + 16 = | 100 + 900 = | 400 × 4 = |
| 20 × 4 = | 900 × 4 = | 90 × 4 = | 13 ÷ 8 = | 300 × 5 = |
| 23 × 2 = | 32 × 2 = | 980 × 2 = | 900 × 4 = | 30 × 8 = |
| 900 + 300 = | 900 × 7 = | 33 × 2 = | 300 + 400 = | 51 ÷ 8 = |
| 200 × 5 = | 330 × 5 = | 680 × 2 = | 900 × 9 = | 609 × 2 = |
| 300 × 2 = | 90 × 7 = | 90 × 9 = | 44 × 2 = | 83 + 6 × 2 = |
| 15 + 5 × 3 = | 40 ÷ 5 + 26 = | 41 - 27 ÷ 9 = | 41 - 36 + 79 = | 15 + 38 - 46 = |
二、填括号
| ( ) ÷ 9 = 2 | ( ) + 557 = 737 | ( ) ÷ 6 = 7 | 8600 - ( ) = 8500 |
| ( ) + 588 = 1105 | 6 ÷ ( ) = 2 | 32 + ( ) = 73 | 73 - ( ) = 62 |
| 2800 - ( ) = 1900 | 6 × ( ) = 12 |
三、竖式计算题
| 38 ÷ 6 = | 906 - 338 = | 558 × 4 = |
| ※ 517 - 326 = | 463 + 148 - 310 = | ※ 349 + 180 = |
