Answer 1

1. (57x2:3)+32x450-[39x(4+2):2+14320)=?

=38+32x450-(39x6:2+14320)

=38+32×450-(117+14320)

=38+32×450-14437

=38+14400-14437

=14438-14437

=1

2.29x3-37+[2000-(17x2+39x1:3)]=

=29x3-37+[2000-(34+13)]

=29x3-37+(2000-47)

=29x3-37+1953

=87-37+1953

=50+1953

=2003

3.68:2+[564:6+(31x2+15x3-117:3)]=

=.68:2+[564:6+(62+45-39)

=68:2+(564:6+68)

=68:2+(94+68)

=34+162

=196
