Question

How do you evaluate `(9+19-4)-(2+2)`?

Answer 1

Use the order of operation PE MD AS

Explanation:

Start by solving what is inside the parenthesis

If you get hurt in PE call an MD ASap.

P stands for Parenthesis so start with the Parenthesis ( ).

(9 + 19 -4) There are no multiplication or division in side the parenthesis so move to the next part ASap. ASap is the same time as soon as possible so do addition (A) and subtraction (S) at the same time working from left to right.

`( 9+19 -4) = (28-4) = 24`

`( 2+2) = 4`

so now remove the parenthesis. giving

`24 - 4` subtract giving

`20`
