Answer:

A. 24 ÷ [6 − 2] × 5 + 6

Explanation:

We are given the expression:

24 ÷ 6 − 2 × 5 + 6

Where could she place brackets in the expression for it to be equal to 36?

We have to follow a rule in mathematics that is referred to as :

PEMDAS

P = Parentheses (Brackets)

E = Exponents

M = Multiplication

D = Division

A = Addition

S = Subtraction.

When given a mathematical expression with a lots of operations embedded in it, we use PEDMAS rule to solve for it correctly.

Option A 24 ÷ [6 − 2] × 5 + 6 is the correct Option to give us 36. This is because, following the PEDMAS rule.

P = Parentheses comes first

24 ÷ [6 − 2] × 5 + 6

= 24 ÷ 4 × 5 + 6

Division comes next

24 ÷ 4 × 5 + 6

= 6 × 5 + 6

Multiplication comes next

6 × 5 + 6

= 30 + 6

Finally , Addition

= 36.

Therefore, Option A is the correct Option, that shows us where the brackets should be placed to give us 36
