一、直接写出得数
| 790 × 2 = | 600 × 3 = | 47 + 34 = | 705 × 2 = | 600 + 600 = |
| 800 × 2 = | 4800 - 200 = | 200 × 3 = | 44 ÷ 9 = | 505 × 2 = |
| 20 × 6 = | 27 ÷ 5 = | 21 × 4 = | 600 × 7 = | 570 × 2 = |
| 605 × 2 = | 9300 - 200 = | 700 × 4 = | 509 × 2 = | 400 + 900 = |
| 780 × 2 = | 20 × 3 = | 70 × 8 = | 80 × 4 = | 680 × 2 = |
| 60 - 16 = | 60 × 3 = | 11 ÷ 2 = | 404 × 3 = | 43 × 2 = |
| 60 × 5 = | 70 × 4 = | 30 × 3 = | 200 × 6 = | 600 × 3 = |
| 707 × 2 = | 400 × 9 = | 600 × 4 = | 700 × 8 = | 600 + 300 = |
| 29 ÷ 7 = | 32 × 3 = | 700 + 800 = | 800 × 2 = | 400 × 9 = |
| 220 × 5 = | 60 × 4 = | 398 - 396 = | 60 × 7 = | 40 × 9 = |
| 330 × 5 = | 22 × 3 = | 70 × 6 = | 40 × 9 = | 69 + 21 ÷ 7 = |
| 8 × 4 + 33 = | 25 - 4 ÷ 1 = | 39 + 47 - 77 = | 54 + 39 - 48 = | 64 - 9 × 5 = |
二、填括号
| ( ) ÷ 2 = 2 | ( ) + 622 = 901 | ( ) - 700 = 3900 | 35 ÷ ( ) = 5 |
| 90 + ( ) = 92 | ( ) + 929 = 1817 | 14 - ( ) = 11 | ( ) ÷ 8 = 7 |
| 2 × ( ) = 2 | ( ) - 800 = 6400 |
三、竖式计算题
| 342 - 295 + 558 = | ※ 525 + 279 = | 622 - 278 = |
| ※ 889 - 827 = | 71 ÷ 9 = | 888 × 9 = |
