1. Calculează: a) 462 - (5 x 27 +21 x 4-5 x 16) = (23 x 5 + 153:9-11 X 6) + 122 x 0 = 1 149 + (56 x 9-27 x 15) - 794 = 674 + (224 x 4 - 32 x 18) - 189 = b) 3 601 – (84 x 21 + 630:14) = (17 x 23 + 26 x 24 + 53 x 9) - (172 x 6) = 1 848 - 567 + (276 x 2 + 15 x 18) + 10:10 = 1 249 +(45 x 6 - 84:3) - 620:5 =

Answer 1

Răspuns:

a) 462-(135+84-80)= 462-(219-80)=462-139=323

(115+17-66)+0=(132-66)+0=66+0=66

1149+(504-405)-794=1149+99-794=1248-794=454

674+(896-576)-189= 674+320-189=994-189=805

b) 3601-(1764+45)=3601-1809=1792

(391+624+477)-1032=(1015+477)-1032=1492-1032=460

1848-567+(552+270)+1=1281+822+1=2104

1249+(270-28)-124=1249+242-124=1491-124=1367
