# How do you simplify -12-4+(8xx4)?

16

#### Explanation:

We'll use the Order of Operations, sometimes known as PEMDAS:

• $\textcolor{red}{P}$ - Parentheses (also known as Brackets)
• $\textcolor{b l u e}{E}$ - Exponents
• $\textcolor{g r e e n}{M}$ - Multiplication
• $\textcolor{g r e e n}{D}$ - Division (this has the same weight as M and so I gave it the same colour)
• $\textcolor{b r o w n}{A}$ - Addition
• $\textcolor{b r o w n}{S}$ - Subtraction - (again, same weight as A and so the same colour)

So with $- 12 - 4 + \left(8 \times 4\right)$ we have a parenthesis:

$- 12 - 4 + \textcolor{red}{\left(8 \times 4\right)}$

$- 12 - 4 + \textcolor{red}{\left(32\right)}$

Now we have addition and subtraction, so we read from left to right and evaluate:

$- 16 + 32$
