Resolver las siguientes operaciones
8-15+(-26)-(-2)
14-[-15-9]-6
[7-(6-2)]-(3-11)
-[9-(-8)]+18-(5-7)
​

Answer 1

Respuesta:

$8 - 15 + ( - 26) - ( - 2) \\ 8 - 15 - 26 + 2 \\ - 7 - 24 \\ - 31$

$14 - [ - 15 - 9 ] - 6 \\ 14 - [ - 24 ] - 6 \\ 14 + 24 - 6 \\ 38 - 6 \\ 32$

$[ 7 - (6 - 2) ] - (3 - 11) \\ [ - (4)] - (3 - 11) \\ [ 7 - 4 ] - (3 - 11) \\ 3 - (3 - 11) \\ 3 - ( - 8) \\ 3 + 8 \\ 11$

$- [ 9 - ( - 8) ] + 18 - (5 - 7) \\ - [9 + 8 ] + 18 - ( - 2) \\ - [17] + 18 + 2 \\ - 17 + 20 \\ 3$
