10-6:2=10-6=4+3=7

Answer 2

a) 4+4x2=4+8=12 b) 10-6÷2=10-3=7 c) 10x(2+2x3)=10x(2+6)=10x8=80 d) 2x[10+10x(6+2x4)]=2x[10+10x(6+8)]=2x(10+10x14)=2x(10+140)=2x150=300 e) 10x{2+2x[3+3x(10-1)]}=10x[2+2x(3+3x9)]=10x[2+2x(3+27)]=10x(2+2x30)=10x(2+60)=10x62=620 f) 10x{475+2x[45+2x(400-298)]}=10x[475+2x(45+2x102)]=10x[475+2x(45+204)]=10x(475+2x249)=10x(475+498)=10x973=9730 g)10÷2+15x3+2x[3x4-(15-2x3)]=5+45+2x[12-(15-6)]=5+45+2x(12-9)=5+45+2x3=5+45+6=50+6=56

Sper că team ajutat!
