三、用竖式计算，带$*$的要验算。(每题3分,验算1分,共49分)
$358 + 457$ $233 - 69$ $*604 - 327$
$266 + 348$ $234 + 79$ $*483 - 195$
$505 - 216$ $*465 - 286$ $*135 + 469$
$536 + 87 + 208$ $427 + 58 - 273$ $500 - 124 - 269$
$810 - 357 - 243$ $716 - 280 + 315$ $321 + 88 + 379$

1. $358 + 457 = 815$
2. $233 - 69 = 164$
3. 解：$604 - 327 = 277$
验算：$277 + 327 = 604$
4. $266 + 348 = 614$
5. $234 + 79 = 313$
6. 解：$483 - 195 = 288$
验算：$288 + 195 = 483$
7. $505 - 216 = 289$
8. 解：$465 - 286 = 179$
验算：$179 + 286 = 465$
9. 解：$135 + 469 = 604$
验算：$604 - 469 = 135$
10. $536 + 87 + 208 = 831$
11. $427 + 58 - 273 = 212$
12. $500 - 124 - 269 = 107$
13. $810 - 357 - 243 = 210$
14. $716 - 280 + 315 = 751$
15. $321 + 88 + 379 = 788$
