Let's see if I can help you ask a better question.

As you can see from your output, the name "cannonhealth" refers to an object which is different than what you expect. So, your question might be, "How do I get a name to refer to a different object? I thought I could just use subtraction." At that point, you might ask, "Well, how did I get that name to refer to an object (75 in this case) in the first place?" Therein, lies your answer. (Hint:  assignment.)

Take care,
Don
