一、写出得数
| 1400 - 400 = | 90 - 32 = | 4000 - 400 = | 500 + 3000 = | 72 ÷ 9 = |
| 14 ÷ 8 = | 300 + 400 = | 4 × 8 = | 300 + 300 = | 91 - 77 = |
| 72 - 63 = | 7600 - 600 = | 5500 - 600 = | 7800 - 300 = | 11 ÷ 5 = |
| 7 × 3 = | 4 ÷ 2 = | 4 × 4 = | 500 + 300 = | 7600 - 600 = |
| 24 ÷ 7 = | 6 × 5 = | 200 + 3000 = | 400 + 200 = | 5100 - 1000 = |
| 400 + 900 = | 12 ÷ 3 = | 9800 - 800 = | 4500 - 1000 = | 400 + 800 = |
| 7 × 4 = | 59 + 37 = | 3 × 5 = | 6 ÷ 2 = | 200 + 300 = |
| 5000 + 300 = | 2000 + 300 = | 24 ÷ 6 = | 1400 - 1000 = | 5 × 8 = |
| 8400 - 600 = | 700 + 100 = | 49 ÷ 9 = | 7600 - 7000 = | 18 ÷ 2 = |
| 7600 - 600 = | 24 ÷ 4 = | 2 ÷ 2 = | 7300 - 300 = | 47 + 47 = |
| 500 + 800 = | 94 - 47 = | 700 + 600 = | 7 × 9 = | 57 + 16 ÷ 8 = |
| 58 + 27 - 39 = | 4 × 3 + 15 = | 70 - 40 - 13 = | 6 × 9 - 15 = | 61 + 10 ÷ 5 = |
二、填括号
| ( ) + 700 = 900 | 1800 - ( ) = 1400 | 10 + ( ) = 86 | 53 - ( ) = 52 |
| ( ) × 9 = 54 | 72 ÷ ( ) = 8 | ( ) + 400 = 1200 | ( ) ÷ 3 = 4 |
| 8100 - ( ) = 7900 | ( ) ÷ 5 = 2 |
三、竖式计算题，带“※” 要验算
| 600 - 186 = | 497 - 148 - 141 = | 13 ÷ 7 = | ※ 114 - 112 = |
| 468 + 465 = | 29 ÷ 5 = | 525 - 370 + 146 = | ※ 418 + 547 = |
