Question

calcula
A) [10-(-2)]-[5-(+12)]=
B) [8-(6+4)]-(5-7)=
C) [1+(6-9)]-(8-12)=
D) 15-{4+[-5-4+(2-3)-16)​

Answer 1

Explicación paso a paso:

[10+2]-[5-12] = 12-(-7) = 12+7 = 19

[8-(10)]-(-2) = [8-10] + 2 = - 2+2 = 0

[1+(-3)]-(-4) = - 2+4 = 2

15-{4+[-9+(-1)-16]} = 15-{4+[-9-1-16]} = 15-{4-26} = 15-{-22} = 15+22 = 37

Answer 2

Respuesta:

A) (10+2) + 5 -12 = 12 + 5 - 12 = 17 - 12 = 5

B) ( 8 - 10 ) +5 - 7 = -2 + 5 - 7= 3 - 7 = (-4)

C) (1 - 6 + 9 ) - 4 = 5 + 9 - 4 = 14 - 4 = 10

D) 15 ( 4 + (-5-4 + (-1) - 16) = 15 ( 4 + ( -9 -1  - 16 ) = 15 - ( -10 -16 ) = 15 + 10 + 16 = 41
