I'm trying to write a program to calculate the present value of the CCA tax shield. I remember in high school we'd use our graphing calculators to program in painstaking formulas so that the calculator would just ask for the variables and then do the work.

The formula is as follows (entering by text didn't really display right, so I used an image):


Now it's been a long time but on the texas instrument calculator the program be essentially "Get X, Get Y etc. etc." then it computes it at the end. On the screen when you ran a program it would prompt "X?" then "Y?" etc. etc.

Is it possible to something like this on the Casio?

I don't expect anyone to to it for me but I don't know where to start. Any direction?

Actually I think I figured it out:
"Enter C"?->C
"Enter D"?->D
"Enter Tc"?->T
"Enter R"?->R
"Enter S"?->S
"Enter N"?->N

R*(1-T)->K

((C*D*T)/(K+D))->W
((1+(.5*K))/(1+K)->X
((S*D*T)/(K+D))->Y
1/((1+K)^N)->Z

(W*X)-(Y*Z)

Probably not the best coding but I get the right result
