Answer 1

Răspuns:

a)13×2+22:2=26+11=37

b)11×(2+66):4=11×68:4=748:4=187

c) (13+7)×3-40:5=20×3-40:5=60-8=52

d)[4+4×(7+2-4) ]:8+20:5=(4+4×5): 8+20:5=(4+20):8+20:5=24:8+20:5=3+4=7

e)114+36:2+2+24:(17-9)=114+36:2+2+24:8=114+18+2+4=

132+2+4=134+4=138

f)144:{40-96:(35-33:3)}=143:{40-96:(35-11)}=143:(40-96:24)=143:(40-4)=143:36=4

g)16:{7×[41-(16×8-119):3]-258}=16:{7×[41-(128-119):3]-258}=16:[7×(41-9:3)-258]=16:[7×(41-3)-258]=16:(7×38-258)=16:(266-258)=16:8=2
