Answer 1

35

Explanation:

-5{3-2[1-4(3-2^2)]}

we work inside out

using PEMDAS

parenthesis, exponents, multiply and divide, add and subtract

the very most inside

(3-2^2)

do the exponents

3 - 4 = -1

replace where it was in the original equation

-5{3-2[1-4(-1)]}

take the next set of parenthesis (bracket are the same as parenthesis)

[1-4(-1)]

multiply

4*-1 = -4

1--4 = 1+4 = 5

replace where it was in the original equation

-5{3-2[5]}

next set of parenthesis

{3-2[5]}

3 - 10 = -7

replace where it was in the original equation

-5 {-7}
