Is There A Free Web Tool For Solving F(x,y) Equations?
So I'm embarassed to say I have a degree in computer science and engineering and I'm tweaking with some formulas I'd like to use in a game I'm building, and my math is very rusty--much worse than I thought. I'm trying to find a free tool or website that would present the results of an f(x,y) function in tabular format so I could just eyeball the results of the equation as I make adjustments to the values for x and y... if that makes sense?
For example, I'd like to see all of the results for the following equation:
f(x,y) = (x - y) / (x + y)
x and y are integers
x >= y
y > 0
x < 100 (or some other value that i could plug in myself)
I've found some tools that can kind of show it in 3D format but I can't seem to find one shows results like this:
x y z
2 1 .3333
2 2 0
3 1 .5
3 2 .2
3 3 0
4 1 .6
Any help would be greatly appreciated! I'm banging my head against the wall...

Excel will work just fine

Unfortunately I don't have Excel at home so I'll have to download something else. Thanks for the suggestion.
