四、用竖式计算，带$*$的要验算。
$366+487$
$536+274$
$*700-294$
$327+425$
$607-482$
$*804-357$
$59+363$
$542-78$
$*393+308$
$78+202+155$
$652-383-79$
$521-347+185$
$198+206-337$
$257+163+277$
$703-176-358$

1. $366 + 487 = 853$
2. $536 + 274 = 810$
3. $700 - 294 = 406$
验算：$406 + 294 = 700$
4. $327 + 425 = 752$
5. $607 - 482 = 125$
6. $804 - 357 = 447$
验算：$447 + 357 = 804$
7. $59 + 363 = 422$
8. $542 - 78 = 464$
9. $393 + 308 = 701$
验算：$701 - 308 = 393$
10. $78 + 202 + 155 = 435$
11. $652 - 383 - 79 = 190$
12. $521 - 347 + 185 = 359$
13. $198 + 206 - 337 = 67$
14. $257 + 163 + 277 = 697$
15. $703 - 176 - 358 = 169$
