Notes:
Algebra uses mathematical notation to solve problems starting in words (replaced with variables)
The multiplication symbol is disregarded in alegbraic expressions and is usually replaced with brackets or a coefficient
Algebra is working toward creating rules that you can use repeatedly in order to solve difficult problems
When making a rule, you need to decide which will be your variable\s
higher order indices are not like terms
Helps to re-arrange the like terms by writing them together
