# Evaluating Algebraic Expressions

# Plug and Chug

Sometimes algebra is a whole lot easier than it appears. Evaluating expressions is one of those times. Just plug in numbers, and chug along performing the order of operations, and voila! To make it even easier, your TI-30XS can do all the calculations for you.

## STEP 1: WATCH THE VIRTUAL CLASS VIDEO AND TAKE NOTES

### Make sure to note the following:

Substitute in the known values, then simplify as usual! Use your calculator to perform the computations if you like. That's all it takes to evaluate algebraic expressions.
