Displaying all numbers as positive
 

Ok hope you guys can help:

A1= x
A2= y
A3= A1-A2

If the answer is a positive number I want it to remain as a positive number
-but-
If the answer is a negative number, I wish for it to be displayed without the "-" sign before the number so it looks like it's a positive number. But I also want it to hold it's negative value so that it can be used later on.

Example:
A1= 5
A2= 8
A3= A1-A2

A3 Normally displays "-3", I want it to display "3".

But I also need it so that if I make A4=A3, then A4 will display "-3"

Hope this makes sense to someone!


Thanks in advance,
Teddy
