四、用竖式计算，带$*$的要验算。
$365+57$
$457+349$
$*402-163$
$857-769$
$275+594$
$*105+866$
$174+638$
$423-68$
$*604-138$
$142+66+318$
$234+513-449$
$903-485-192$
$500-203+316$
$740-256-265$
$125+469-398$

1. $365 + 57 = 422$
2. $457+349 = 806$
3. 解：$402 - 163 = 239$
验算：$239+163 = 402$
4. $857 - 769 = 88$
5. $275 + 594 = 869$
6. 解：$105 + 866 = 971$
验算：$971 - 866 = 105$
7. $174 + 638 = 812$
8. $423 - 68 = 355$
9. 解：$604 - 138 = 466$
验算：$466+138 = 604$
10. $142 + 66 + 318 = 526$
11. $234 + 513 - 449 = 298$
12. $903 - 485 - 192 = 226$
13. $500 - 203 + 316 = 613$
14. $740 - 256 - 265 = 219$
15. $125 + 469 - 398 = 196$
