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?
