I try to create a simple "program" om my classpad 330 plus.

I use the program function in the classpad and try to run this code:


Input A, "skriv inn a verdien"
Input B, "skriv inn b verdien"
Input C, "skriv inn c verdien"
Print -B+√(B^2-4*A*(C)/2*A

When i run it i just get this message:

"Non-real in calc"

But when i have switch the letters over to numbers, i get a solution.


So what im I doing wrong?
