Solving a System Using Matricies (It's alot like the elimination method!)

This livescribe video parallels solving a system of equations using matricies with reduced row echelon and solving a system using eliminations.

Logarithms and Exponential Functions

Here are a couple of videos that I went ahead and created that tackle using logarithms to solve problems that involve exponential equations.

Video 1:  This video is just an introduction on how we can use logarithms to solve problems without knowing any properties of logarithms.

Video 2:  This video is the second in the series, it tackles natural log and also a couple properties of logarithms that can be constructed through basic understanding and a little magic!

Welcome to LC's Algebra 2 blog

The purpose of this blog is to share thoughts, ideas, and insights that will help teachers and students to expand their understanding of mathematics.  Nothing that you find here is meant to be perscriptive, instead, the ideas presented are just meant to show you an additional approach to a topic.

The contributions that you will find here come from teachers who are excited about getting better at their craft.
