Question

Whats the answer to (5² -4) ∙ 2 – 18

Answer 1

Solving the equation
`(5^2 -4) \cdot 2 -18` we get 24

Explanation:

We need to solve the equation
`(5^2 -4) \cdot 2 -18`

We will solve using DMAS rule i.e first bracket will be solved, then multiplication and at the end subtraction will be done.

First we will solve the bracket

`(5^2 -4) \cdot 2 -18\\=(25-4) \cdot 2-18\\=21 \cdot 2-18`

Now multiply 21 by 2

`=42-18`

Now subtract

`=24`

So, solving the equation
`(5^2 -4) \cdot 2 -18` we get 24
