2. OUTLINE:
1- identify the need of order to perform operations.
2- Simplify the expression according to the order of
operations.
3. THE EXPRESSION:
We need to simplify this expression down to one number (find the answer).
+(3x5)-2
325
5
But where do we start??
There is a certain order we need to follow when we simplify
this expression, or we will get the wrong answer. This is called…
Order of operations
4. Going left to right (like when
reading)
• Do anything in Parentheses
• Start over and do any Exponents
• Start over and do any
Multiplication and Division
• Start over and do any Addition
and Subtraction
