The second link I visited under the Merlot webpage math listings was
Developmental Mathematics (60). After approximately ten minutes, I found a link
that lead me to an exercise developed and presented by Mr. Garret Heath,
entitled "System of Equations". Here a system for plotting lines is presented
for equations, and shows where lines intersect as well as accords you the
solution to any system of two equations. I spent several hours manipulating
equations and derived a range of solutions, from intersects that were unique to
coincidental. With this link I was able to work with some of the home work
assignments, from chapter eight (Mathematical Ideas), as well as avail myself
self-instruction. Personally, I find there is something about working on
solutions for equations and then graphing them, accordingly, rather absorbing (I
really do not have an explanation for this curiosity). Here, I suspect that the
content Heath has developed (and made available free of charge) would help,
measurably, any student attending pre-algebra through intermediate algebra
classes. Consequently, the model(s) present examples and concrete explanations
of the solutions that are educationally noteworthy, especially for struggling
algebra students. As can often be the case when an instructor?s teaching ability
and a student?s comprehension ability do not a match make, this link allows
both parties to experiment with equations and solutions by developing equations
that demonstrate (and are confirmed) unique, infinite, coincidental, and no
solution which coincide with negative, positive, zero, and undefined slopes. All
the aforementioned can be accomplished without the pressure of a classroom
environment and, therefore, should reduce the stress load for both instructor
and student by augmenting learning exercise(s) that supplement course content,
and neither party need worry about grades. Whether an expert or a novice with
the computer, once one arrives upon Heath?s link, all alike will find this
software operations friendly because there are only two data entery fields, to
contend with, and three options for arriving upon the solution to any two
equations.

I spent about 10 mintutes on the material and tool. The tool was very helpful. I
could use any numbers and itwould still give me an answer. It was easy to use
the tool, the instructions were short, and all you had to do was pick random
numbers. You could also challenge the tool, and see if you can give it problem
that was difficult to solve. This would help students in the classroom alot. the
tool is quick and easy, good for showing examples without the lengthy drawing
on a whiteboard, chalkboard, or on paper. The answers and explinations that were
given were great.
