We've been doing a lot of increasing or decreasing variables by 1 and reassigning them to the original variable. Might there be a shortcut?

Isn't that handy? These assignment operators perform the operations they're supposed to but automatically reassign the results to the variables before them.

Psst: we can also use -=, *=, /= to shorten our code.

Yikes! Maybe we need a combination of both symbols?
