Overview

Stored values only matter once you can combine and compare them. You'll calculate with Python's arithmetic operators, assemble readable messages from variables and text, put those skills together to solve real formula-based problems, and then evaluate comparisons and logical conditions that produce the true-or-false answers programs rely on to make decisions later.
