Question

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

Answer 1

`91` using PEMDAS

Explanation:

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

`16+5(15)`

Multiply to get

`16+75`

Add to get our final answer of

`91`

Hope this helps!

Answer 2

`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(15)` 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!
