About

Over the next four weeks, we will meet semi-weekly—on Mondays and Fridays—to go over everything you need to know about logarithms to achieve a 100% score on the Khan Academy Unit test. We will cover an introduction to logarithms, the constant ee

 and the natural logarithm, properties of logarithms, the change of base formula for logarithms, and solving exponential equations with logarithms and exponential models. We will also have additional sessions some Tuesdays and Thursdays to review what we have previously learned in the series.
Sessions are relatively slow-paced.

✋ ATTENDANCE POLICY

Attendance is, of course, optional. You are free to only attend the sessions on concepts that you want to go over. However, as with most concepts in mathematics, knowledge will build incrementally. Additionally, you are free to join sessions late or leave early; just let me know!
