Solving Algebraic Equations Part 1

Updated on November 26, 2012

Solving “Escalator Type” Algebraic Equations

In order to simplify what I was being taught in Algebra my mind came up with cartoon like descriptions for the equations I was expected to solve. I found that there were only two kinds of algebraic equations. In my mind I saw every equation I was asked to solve as being either a “Wall Type” or an “Escalator Type” equation. In this article I will deal with the “Escalator Type” equation.

An Escalator Type equation in algebra has only two terms and can be written with the equal sign between the two terms.

Here are four examples:

3X = 8

5a/3 = 9

3x/4 = 2/5

ax² = k

In order to solve an “Escalator Type” equation I came up with some simple rules that worked for every single “Escalator Type equation.

1. The equal sign turns into an escalator.

2. Numbers or letters can only move diagonally along the escalator. (Never vertically.)

3. When a number or letter is moved the number one is left behind like a calling card.

Following are the steps I went through in my mind to solve this kind of equation.

I used a program called Flash by Macromedia to create my animation exactly as I saw it in my minds eye and here is the animation clip by clip.

Every Escalator Type Equation has this Form

      Yes I have created a number of products to help children master mathematics. I created MathTutor an animated interactive program like the one in the video above to work on PC or MAC and it teaches all the basiscs of arithmetic. I also made an audio designed to help children be more confident and learn more effectively. You can send me an e-mail or visit my site if you want more details. Thanks for your interest.
