Question

Calculează: (846 - 392) + (173 + 97) – 690 = (1 912 + 4 855) - (8 106 - 7 645) + 3 694 = 24 144 - (6 442 + 658) + (18 544 - 15 319) - 20 269 = (21 618 - 17 549) + (10 502-9408) + (13 580 - 12 645) = 600 000 + (55 746 +24 286) - (79 433 - 47 973) = ​

1. (846-392)+(173+97)-690

=454 + 270 -690

=724-690

= 34

2. (1 912 + 4 855) - (8 106 - 7 645) + 3 694

= 6 767 - 461 + 3 694

= 6 306 + 3 694

= 10 000

3. 24 144 - (6 442 + 658) + (18 544 - 15 319) - 20 269

= 24 144 - 7 100 + 3 225

= 17 044 + 3 225

= 20 269

4. (21 618 - 17 549) + (10 502-9408) + (13 580 - 12 645)

= 4 069 + 1 094 + 935

= 5 163 + 935

= 6 098

5. 600 000 + (55 746 +24 286) - (79 433 - 47 973)

= 600 000 + 80 032 - 31 460

= 600 000 + 48 572

= 648 572
