Question

F)4-[2-(6+7)]-(7+9-3)

G)-[(11-12)-(-7+9)-[(3-6)+14]

H)2-[(4-7)+1]-3

I)-{-[7-(2+5+7)]+11}+13

J){-(4-3)+[10-(31-27)]+3

K)-[4+2.(-5):(-2-1)

L)30-3(-4)-30:(-10)

M)[6.(-7+2)+6]:[(-2).(-3)

N)[(2-3).2+3.(-2+1)]:(-1-4)​

Answer 1

Resposta:

F) 4 - [2- 13] - (7+9-3)

4 - [2-13] - 13

4- (-11 - 13 = 28

G) -[(11-12)-(-7+9)-[(3-6)+14]

-[(-1) - (2) - [(-3)+14]

-(-3 - 11 = -14

H)2-[(4-7)+1]-3

2- [(-3 +1]-3

2-(-2 - 3= 1

I)-{-[7-(2+5+7)]+11}+13

-{7-14]+11}+13

-{-(7 +11} +13

-4+13 = 9

J){-(4-3)+[10-(31-27)]+3

{-7+[10-4]+3

-7+6+3=2
