Question

elimina paréntesis y resuelve las operaciones. A _ -2+(-7+3)-(-5). B_ (-12)+5-(-7+11)

C_-(5-9+1)+(-2+3-7)
D_-(+5)+(-4)-(3+5)-(-9)​

Answer 1

Respuesta:

A = -2+(-7+3)-(-5)

A = -2 -7 +3 +5

A = -9 +8

A = -1

B = (-12)+5-(-7+11)

B = -12 +5 +7 -11

B = -23 +12

B = -11

C = -(5-9+1)+(-2+3-7)

C = -5 +9 -1 -2 +3 -7

C = -15 +12

C = -3

D = -(+5)+(-4)-(3+5)-(-9)​

D = -5 -4 -3 -5 +9

D = -17 +9

D = -8
