Question

como resuelvo los siguientes signos de agrupacion a.-8+[-(13+(-5))-14+16]-15 b.[9+(-4)]-[-32+(-5+4)]+16 y c.17-[4+(-3+5)-(-8+7)+3]

Answer 1

a.-8 + [-(13 + (-5) ) - 14 + 16] - 15
= -8 + [-(13 - 5) + 2] - 15
= -8 + [-8 + 2] - 15
= -8 - 6 - 15
= -29

b.[9 + (-4)] - [-32 + (-5 + 4)] + 16
= [9 - 4] - [-32 - 1] + 16
= 5 + 33 + 16
= 54

c.17 - [4 + (-3 + 5) - (-8 + 7) + 3]
= 17 - [4 + 2 + 1 + 3]
= 17 - 10
= 7

Answer 2

a. -8+[-(13+(-5))-14+16]-15 
    -8+[-(13-5)-14+16]-15
    -8+[-13+5-14+16]-15
    -8+(-6)-15
    -8-6-15
    = -29
        
b. [9+(-4)]-[-32+(-5+4)]+16
    [9-4]-[-32+(-1)]+16
    5-[-32-1]+16
    5-[-33]+16
    5+33+16
    = 54

c. 17-[4+(-3+5)-(-8+7)+3]
    17-[4+(2)-(-1)+3]
    17-(8+1+3)
    17-8-1-3
    = 5
