Answer 1

Răspuns:

2+6+9-10+7=8+9-3=17-3=14

100-4x8+16:2=100-32+8=68+8=76

13-8+61-40=5+21=26

1x1+1-1:1+1=1+1-1+1=1+0+1=1+1=2

2x3x3:6=6x3:6=18:6=3

(1x1+1:1+1):1x1=(1+1+1):1=3:1=3

27:3x7+15:5x4=9x7+3x4=63+12=75

(22-19)x(11-7)=3x4=12

(7x8-6):5=(56-6):5=50:5=10

(20:10)x(24:4)=2x6=12

(7x7-35):2=(49-35):2=14:2=7

(64+8):9+38=72:9+38=8+38=46

250-(13+6x9)=250-(13+54)=250-67=183

12:2+24:3+2x4x7-9x2:3=6+8+8x7-18:3=6+8+56-6=14+50=64

(15+18:9+23):10=(15+2+23):10=(17+23):10=40:10=4

(5x5-14:2):(45:5-21:3)=(25-7):(9-7)=18:2=9

Explicație pas cu pas:

Intai se fac operatiile din paranteza

Imultirile si impartirile se efectueaza inaintea adunarilor si scaderilor.
