Need help with basic subtraction formatting

lukecplusplus (15)
I am writing a program that is supposed to compare how old someone is in relation to recent events. I have gotten to the stage where I can put in some of the events but I am having some issues on how the formatting works. I studied this a few days ago but I cannot find my old resources on how to do it. Thank you in advance for helping.

As gwslow pointed out, assignments go right to left, not left to right.

Um, are you sure? You didn't update the code in your post.
