Need help with these class errors on a basic math program

dnun99 (6)
Getting tons of errors all of a sudden after adding a few things to this. I've been looking up lectures and guides and I can't get it to work. I've tried tracing my steps back and trying to start from scratch but cant seem to get it to work.
