Cant solve the equation as the variable is coming undefined! Any help appreciated
Yes, the variable y is undefined at the definition of A, and so is the variable h (but Prime will only marke one error in a statement).
Prime works (reads) from left tot right AND top tot bottom.
If you move the definition of A to the right or below the definition of y, the error should be gone.
Then you can evaluatie A.
Succes!
