Answer 1

Respuesta:

A)-15

B)35

C)12

D)-3

E)8

F)-3

G)-34

Explicación paso a paso:

A) - 5(2+1)= - 5(3) = - 15

B)18+(9+3+5) = 18+(17) = 18+17 = 35

C) - (4-16) = - (-12) = 12

D) 14-(15)-(4+2-3-(1))= 14-15-(2) = 14-15-2 = - 3

E) 5-12-(-15) = 5-12+15 = 8

F) 3-(4-(-2))-(9-(5+4))= 3-(4+2)-(9-(9)) = 3-6-0 = - 3

G = 15÷-3 = - 5

H) 7(-3) + (2-15) = - 21 - 13 = - 34

Answer 2

Respuestas:

a. - 5 * [ ( - 6 ) ÷ ( - 3 ) + 1 ] =

$- 5 * [(\frac{-6}{-3}) + 1] =$ $-5*(2 + 1) =$ $(-5)*(3) = -15$

b. 18 + [ 9 - ( - 3 ) + 5 ] =

$18 + [9 + 3 + 5 ] = 18 + 17 = 35$

c. - [ 4 - ( 16 ) ] =

$- [ 4 - 16 ] = - [ - 12 ] = + 12$

d. 14 - ( 8 + 7 ) - [ 4 + 2 - 3 - ( - 4 + 5) ]

$14 - ( 15 ) - [ 4 + 2 - 3 - ( 1 ) = 14 - ( 15 ) - [ 4 + 2 - 3 - ( 1 ) ] =$

$14 - 15 - [ 4 + 2 - 3 - 1 ] = 14 - 15 - [ - 4 + 6 ] = - 1 - [ + 2 ] =$

$- 1 - 2 = - 3$

e. 5 + ( - 12 ) - [ - 3 - 12 ] =

$5 + ( - 12 ) - [ - 3 - 12 ] = 5 - 12 - [ - 15 ] = - 7 - [ - 15 ] = - 7 + 15 = 8$

f. 3 - [ 4 - ( 5 - 7) ] - { 9 - [ 5 - ( - 4 ) ] } =

$3 - [ 4 - ( - 2 ) ] - [ 9 - [ 5 + 4 ] ]$ =

$3 - [ 4 + 2 ] - [ 9 - [ 9 ] = 3 - [ 6 ] - [ 9 - 9 ] = - 3 - 0 = - 3$

g. 15 / ( - 3 ) =

$\frac{15}{(- 3)} = - 5$

h. 7 * ( - 3 ) + [ 2 + 3 ( - 5 ) ] =

$7 * ( - 3 ) + [ 2 + 3 ( - 5 ) ] = - 21 + [ 2 + ( - 15 ) ]$

$- 21 + [ 2 - 15 ] = - 21 + ( - 13) = - 21 - 13 = - 34$
