Unit 1 – Equations
Equations
To solve an equation, use your calculator.
STEPS:
1. Menu
2. Algebra (#3)
3. Numerical Solve (#1)
4. Type in equation
5. Put a comma (,) at the end, and then the variable afterwards
Ex 1: 2x + 5 = 6x – 3
Ex 2: 6(x + 1) = 2/3(9x + 12)

Dimensional Analysis
Must Know Conversions!!!!

Unit 2 – Inequalities
Inequalities:
o Solve the same as equations
o If there is a negative with the variable, flip the sign
o Variable must always be on the left, the answer must be on the right
o > and < are open circles on the number line
o ≤ and ≥ are closed circles on the number line
o > and ≥ are to the right on the number line
o < and ≤ are to the left on the number line
