Question

Resolva as expressões numéricas A) 5+(3-1)= B) (13-4)-8= C) 12-(7-3)= D) (20-3)+(7+5)= E) 5-[5-(4-6)]+ F) 3[5-(4-6)]= G) 2+[8-(7-5)+3]= H) -8[4-(7-13)-17+5= I) 1-[5+(1-9)]=

Answer 1

Resposta:

A) 5+(3-1) = 7

B) (13-4)-8 = 1

C) 12-(7-3) = 8

D) (20-3)+(7+5) = 29

E) 5-(5-(4-6))

5-(5-(-2))

5-(5+2)

5-(7)

5-7

-2

F) 3(5-(4-6))

3(5-(-2))

3(5+2)

3(7)

3×7 = 21

G) 2+(8-(7-5)+3)

2+(8-(2)+3)

2+(8-2+3)

2+(9)

2+9

11

H) -8(4-(7-13)-17+5

-8(4-(-6)-17+5

-8(4+6-17+5

-8(-2)

16

I) 1-(5+(1-9))

1-(5+(-8))

1-(5-8)

1-(-3)

1+3

4
