--Version Info--

v1.1 - this version,  made smaller, and a few other minor changes
v1.0 - original version,  solves 1, 2, and 3 variable equations as well as
         1 variable inequalities

--Program Info--

	This program is very useful for solving equations.  This program 
will solve equations with one variable, two variables, and three variables.  
It also solves inequalities with one variable.  All the answers are shown 
in decimal form and fraction form (if there is any).  I found this program 
very useful in math classes.  

	For the 1 variable solver I separated the equation in two for the 
part before and the part after the = or other symbols (>,<,etc).  Then I 
used solve( to solve the equation.  Then I tried the equation with x being 
1 more or 1 less than the answer to find out whether the answer is = or < 
or >, etc.  

	For the 2 variable solver you have to input the two equations as 
aX + bY = C.  Then the program uses the rref( [A] ) to solve the equation.  

	For the 3 variable solver you have to input the three equations the 
same way as the 2-equation solver except with three vars.  It also uses the 
rref( [A] ) to solve the equations.  

I hope you find this program useful!  (I did)  If you have problems with 
this program you can e-mail me at:  kentaro1087@hotmail.com
