Lesson 1 #31

For this problem, there are multiple operations to be performed.  When there is more than one operation, you need to use the correct order of operations when you carry out the operations or else you may get an incorrect answer.

The order of operations is PEMDAS

Parentheses (Parentheses are not an operation.  They are an indicator to perform some other operation that is in parentheses first)

Exponents

Multiplication/Division (from left to right whichever comes first)

Addition/Subtraction (from left to right whichever comes first)

Sometimes it is useful to start by identifying how many and what type of operations you need to perform.  This will keep you from jumping in and performing the first operation you see.

The 2 operations that need to be performed are circled below.

Now remember, multiplication have the same priority in the order of operations, but we work from left to right.  So the order is as follows.

1:  Division

2. Multiplication

The steps are shown below.
