Calculati in detaliat va rog frumos
[1+(3x20-25x2)+7x7]:6+942:6
[100:(10:5+56:7)+90]:10
[3x(2+6-3)+(45:9+2x5)-5]:5
[2+(3x5-7x2)+54:9]x8-(8x8+8)
[10+2x(16:4+27:9)]:3
2+[3+2x(6-1):5+63:9-41]
2+[2x2+2x(2:2+2x2)]:7

Ajutati ma va rog frumos.Va dau 20 de coroane si 80 de puncte.REPEDE

Answer 1

(1+10+7*7):6+157=(11+49):6+157=167
(100:10+90):10=100:10=10
(3*4+15-5):5=(20+10):5=6
[(2+1)+6]*8-72=9*8-72=0
(10+2*7):3=8
2+3+2+7-41=14-41=-27
2+14/7=4
