Answer 1

№9

1)125 * 2304 + 653 * 1000 - 851 * 106 = 288000 + 653000 - 90206

2) 457100 + 1423 * (6123 - 5941) - 11007 = 457100 + 1423 * 182 - 11007 = 457100 + 258986 - 11007 = 705079

3) 382 * 905 + 618 * 905 = 905 (382 + 618) = 905 * 1000 = 905000

4) 749 * 709 + 251 * 709 = 709 (749+251) = 709 * 1000 = 709000

5) 1027 * 378 - 72 : 36 * 905 - 628 : 4 = 388206 - 1810 - 157 = 386239

6) (650 * 15 + 350 * 15) * 0 + 800 : 32 - 25 = 0+25-25 = 0
