Dear Mr Donald Catto
I have using substarct method to know the status of the value, first, i substact var1 to var2, then var1 to var3, and finally var2 to var3.. The problem is i dunno how to keep the information to show which one is more bigger, or there are same, without changing the status of var1, var 2 , and var3.

I dun post a code at here is because my code is not complete yet.. i think now my problem is more to the concept prolem than programming problem..

I am still working on it, hope can come out the result tomolo, then i can show it at here...
