## Smart formulas preset spreadsheet?

(OP)

What I want to do is basically to set up a spread sheet that contains a bunch of formulas.

For example lets us the F=ma formula to illustrate.

I dont know any of these numbers initially...

Is there a way that I can set up a formula that will work out the remaining value if I know just two of these variables.

the first case f= ? I know m and know a

the second case i know f and I know m a=?

last one I know a and I know f m=?

I want to have input cells that I can enter any combination of two variable and get the third one out.

I want to use the minimum number of cells to achieve this too.

How do I do this in Excel.

I have seen it done somewhere I can remember but I want to have a preset spreadsheet with formulas to allow me to plug in known values and work things out with multiple arrangements lying around.

Is this possible?

Otherwise, you'd need to use some of the Solver and VBA functionality

= if (a = "solve",F/m,if(m = "solve", F/a,if(F = "solve", m*a)))

for more complex equations, the same thing can be accomplished in a user defined function.

= SolveFMA(F,m,a)

Im looking to make a spreadsheet with a lot of formulas. Kinda plug it in to get quick results etc.

I am inclined to go for the 4 cell approach.

3 cells for input and one for out put.

As for TKSolver I have not heard of it but I have blown my budget on MS Project so I can update my skills as everyone seems to want engineers to drive MS Project at the minute.

anyhow

Thanks
