# How do you simplify 16 + 5(11 +4) using order of operations?

May 14, 2018

$91$ using PEMDAS

#### Explanation:

According to PEMDAS (Parenthesis, Exponents, Multiplication, Division, Addition, Subtraction), we simplify the terms in the parenthesis. We get

$16 + 5 \left(15\right)$

Multiply to get

$16 + 75$

$91$

Hope this helps!

$91$

#### Explanation:

Keep in mind what the order of operations is! Remember:
Parentheses - Exponents - Multiplication - Division - Add - Subtract, starting with Parentheses.

So, in this problem, you would start with $11 + 4$ which is $15$. You would then do multiplication with $5 \left(15\right)$ as there are no exponents and obtain $75$. After this, you can simply add 16 to get $91$!

You could also take $5$ and multiply it by $11$ and $4$ separately to obtain $75$ without actually adding $11$ and $4$. That would look like $55$ (from 511) and $20$ (from 54), adding to $75$ which is the same as before!
