5.用竖式计算:
356+237= | 620-338= | 505-238= | 657+276= |
700-537= | 256+744= | 542-476=验算: | 354+177=验算: |
4.口算.
49+21= | 130+30= | 150+70= | 84-25= |
410-110= | 900-200= | 36+32= | 72-5= |
75+25= | 808-108= | 730-230= | 570+100= |
18.列竖式计算:
0 163212 163220 163226 163230 163236 163238 163242 163248 163250 163256 163262 163266 163268 163272 163278 163280 163286 163290 163292 163296 163298 163302 163304 163306 163307 163308 163310 163311 163312 163314 163316 163320 163322 163326 163328 163332 163338 163340 163346 163350 163352 163356 163362 163368 163370 163376 163380 163382 163388 163392 163398 163406 199269
28×114= | 406×25= | 150×48= |
77×134= | 807×60= | 18×498= |
