Question

Suma, resta, multiplicación y división con Z

-3(4-6)-2{5[3-5(-7+5)-3]}=

-3{-4[-5(-6x2-7)]} =

4-2{3[5-2(5-6)-7]+10}+17 =

2 {[3+2 (4-3)-2 (6-8)-5]} =

3{4(2-7)-11-2[3(-5-1)]} =​

Answer 1

-3(4-6)-2{5[3-5(-7+5)-3]}= -9

-3{-4[-5(-6x2-7)]} = -23

4-2{3[5-2(5-6)-7]+10}+17 = +17

2 {[3+2 (4-3)-2 (6-8)-5]} = -1

3{4(2-7)-11-2[3(-5-1)]} =-17
