Linux vs PC Problem

This program works fine on my pc.

The problem is that when I run it remotely on a linux based machine, and I loop back to enter another expression, on the third expression, it ignores the first number of the expression.

Is there any way to make this work on linux?

I don't really care if it doesnt work on my PC.

Thanks!

Whoa my bad. haha

I figured out the problem.............user error

Unfortunely that problem is all too common
