Answer:

24

(twenty - four)

Explanation:

Again we want to evaluate this using BPEMDAS

Which tell us in order which operations we do

Remember BPEMDAS means

Brackets

Parenthesis

Exponents

Multiplication/Division (going left to right)

Addition/Subtraction (going left to right)

{3 + [−5 (2−4) ÷ 2]} x 3

==> first we perform all operations in the innermost bracket

[3 + (−5(-2) ÷ 2)] x 3

==> we do the same thing as the first step, the operations in the inner most parenthesis. there is only multiplication and division here so we perform them going left to right

[3 + (10 ÷ 2)] x 3 ==> multiplication first because its before the division in the parenthesis

(3 + 5) x 3 ==> division next

==> next we do the final operations in the parenthesis 3+5

8 x 3

==> finally the multiplication

= 24
