Here, we can solve this equation by using the order of operations. This tells us the order in which we must solve the equation.

P -parentheses
E -exponents
M -multiplication
D -division
A -addition
S -subtraction

First, we must complete the problem in the parentheses.


When we put this back into the equation, we see the following.


Next is exponents. We can see that this equation has no exponents. It also has no multiplication or division, so we can skip right to addition. When doing addition, we solve in the order of left to right.
The following should be done first because it is the first addition problem from left to right.


Then, we plug this back in to get the following.


We continue doing all of the addition from left to right and must solve this problem next.


Then, we plug it back in to get the following.


This gives us our final answer.
