Order of Operations
How do you remember the order of operations?
1.1-1.2 Expressions & Numbers
Order of operations is used to simplify algebraic expressions.
Example of an algebraic expression:
Simplify ExpressionsTo simplify any expression just add like terms.
Like terms are terms that contain the same variables raised to the same power.
Only the coefficients of like terms are different.
Examples
