ALGEBRA
Written by: John Robinson
ALGEBRA represents my first serious
attempt at programming. As a high
school algebra teacher, I wanted to
write a program that I could use as
a meaningful introduction to solving
equations. I was pleased with my
students' responses to my program.
I entered it in a software contest
sponsered by the Milwaukee Area
Commodore Enthusiasts (M.A.C.E.). I
won first prize in the educational
catagory.
ALGEBRA gives you endless practice
in solving algebraic equations. After
an equation is chosen, your goal is
to solve it as quickly as possible.
To solve the equation, you must alter
it by using any of the following
commands (you can view these from
within the program):
ADD -- Add a constant to the
equation.
SUB -- Subtract a constant from
the equation.
MUL -- Multiply the equation by
some constant.
DIV -- Divide the equation by some
constant.
COM -- Combine the like terms in
the equation. This cleans
things up a lot sometimes.
DIS -- Distribute through the
equation. This changes
such things as 3(X-1) to
3X-3. After this is done,
COMbining is usually most
effective.
When you finally get the equation to
look something like 'X=17', you have
solved the equation. After solving
the equation, the original equation
will be shown with the calculated
value of X inserted into the correct
positions. This is done so you can
check the validity of your answer.
After solving an equation, you can
try to solve a new equation or you
can try to solve the same equation by
using different (and maybe more
effective) steps.
