Ok, heres the deal. Im trying to create some basic programs that will ask me for the 3 variables in the equation such as f=mxa or c2=a2+b2 (2's mean squared) and I have a whole lot more.. What I want each of the programs to do is just pop up asking me for each variable.. and ill type them in.. and for which unknown one I just type in 0 or someting to let it know thats what im trying to find.. I forgot how to program then so thats why I nee dhelp starting al over again.. thanks... im really in a rush though cuz midterm is coming up and im gonna need to do it fast. so thats why im trying to make these mini programs to eliminate typing mistakes/ and just make the whole process faster for completing each question. I dont really have much time to learn bymyself right now. so if anyone of u guru's would be kind enough to whip up a simple program for lets say f=mxa and it asks in beginning what f is and m is and a is.. and suppose I put in a 0 for a, then it finds a etc.. that way I can learn much faster and ill just make a ton of programs and put in my equations into that code.. thanks

i dont really get what you are saying (u type in f and m and it gives u a right?), but, it should look like this...

"enter first number"?[->]F
"enter 2nd number"?[->]M
F/M[->]A

--edit--
for the c^2=a^2+b^2 one,

"anter number for a"?[->]A
"enter number for b"?[->]B
a^2+b^2[->]C

Hey thanks for the code, Im also trying to get a program that wil ask for all of the variables, A, B and C.. and if I say I want to find the unknown "A" for instance in c^2=a^2+b^2, it will automaticaly solve the equationt to get A

[huhn_m]

why don't you use the built in equation solver?

((EQUA->SOLVER)

[Marco]

Would be toooooo easy I guess

Girn, se Equa! But if you just want to know how you might solve such problems with Casio Basic programs not using EQUA, it?s this like:

"A?+B?=C"
"A"?->A
"B"?->B
"C"?->C
ClrText
If A=0 Then
"A"
Sqrt (C-B?)
Else If B=0 Then
"B"
Sqrt (C-A?)
Else "C"
A?+B?
IfEnd
IfEnd

Note: The square root is meant by "sqrt"; you have a special char on your calc, so don?t try to type in "sqrt", it?ll not work!

---Edit:---

I forgot to note: you have to set unknown vars to 0 in this piece of code

[Bob Vila]

Thanks I tried it but calc is giving error at this part "If A=0 Then"

delete the "Then" and put it on the next line

[Bob Vila]

heh, forgot about the output

//after all previous crap
ClrText //if you want to, if you dont want to, change the #'s on the next command
Locate 1,1,A
Locate 2,1,B
// etc

[Bob Vila]

k, i'm doing this off the top of my head now, i will try it on my calc ;-)

[Bob Vila]

heres the square root program... if you want to find A or something, just enter 0

ClrText
"A"?[->]A
"B"?[->]B
"C"?[->]C
If A=0
Then C^2-B^2[->]D
(squarerootkey)D[->]E
"A="
Locate 3,7,E
IfEnd
If B=0
Then C^2-A^2[->]F
(squarerootkey)F[->]G
"B="
Locate 3,7,G
IfEnd
If C=0
Then A^2+B^2[->]H
(squarerootkey)H[->]I
"C="
Locate 3,7,I
IfEnd

[Bob Vila]

f=mxa program

ClrText
"F"?[->]A
"M"?[->]B
"X"?[->]C
"A"?[->]D
If A=0
Then BxCxD[->]E
ClrText
"F="
Locate 3,1,E
IfEnd
If B=0
Then A/(CxD)[->]F
ClrText
"M="
Locate 3,1,F
IfEnd
If C=o
Then A/(BxD)[->]G
ClrText
"X="
Locate 3,1,G
IfEnd
If D=0
Then A/(BxC)[->]H
ClrText
"A="
Locate 3,1,H
IfEnd

admittedly this isnt the most effient code, but it works

[huhn_m]

I still don't get why you don't use the build in solver.

You should also be able to rewrite the formula to the value you nedd ...
These formulas are eays ...

[CrimsonCasio]

i find that writing a program for something your calc can already do is good for learning how to do it, but thats just me
i tend to be better at remembering words than numbers.
