How do I calculate variable addition such as:
"x+x=2x" using Excel?

How do I calculate "x+x=2x" using Excel?
 

if x1 is in cell a1 and x2 in cell a2 then =a1+a2 give the sum

if x is in a1 the =2*a1 gives you twice

How do I calculate "x+x=2x" using Excel?
 

I mean, how would I calculate x+x without having to assign a number to x?
If I put:
A
1 x
2 x
3 =a1+a2 ( Get the error #VALUE!) ...I want it to show "2x"

How do I calculate "x+x=2x" using Excel?
 

if x is in both a1 and a2 is thsi what you are looking for?

=CONCATENATE(COUNTif(A1:A2,"x"),"x"

Hi mel

didn't realise you had multi-posted .... normally, not necessary (and
frowned on) within these newsgroups ...

How do I calculate "x+x=2x" using Excel?
 

I'm trying to do algebraic operations on the cells
so if I enter (all in a single cell):

2x+2y+y -----I would get---- 2x + 3y ----------in the same cell when I
press enter
x+y+z -----I would get ----- x+y+z -----------in the same cell when I
press enter
10+x+4x+y+y -----I would get----- 10+5x+2y---in the same cell when I press
enter

I hope that explain what I'm trying to do better, sorry I was vague before.

I apologize. First time using the discussion group and accidently posted
twice without realizing it.

You cannot do that with Excel worksheet functions. You will certainly not be
able to enter something in a cell, and then have the contents of the cell
change to the result, with the functions. And to use undefined variables as
you describe would be exceedingly complex.

However, you could write a routine in VBA which could parse out your entries,
and then give you a result. And put this routine into an event triggered macro
to change the cell contents as you describe.

XL doesn't support symbolic math. Use a program such as Mathematica or
Maple or a competitor that I don't know about.
