Algebra I

Today we discussed
We discussed how to solve equations with radicals.  Most notably, we must isolate the radical so that we can square both sides (using inverse operations again to solve equations!).  We also reviewed simplifying radical expressions - recall that radicals in the denominator are not permitted if an expression is to be in simplest form.

Pre-Algebra

Today we discussed
We used a practical application of percents today by calculating percent of change.  When we get a negative answer, it means we have a decrease so negative answers are perfectly fine.

Recall that percent of change is calculated as follows:
