In the last section, you printed text to the screen. But those programs couldn't remember anything. Every time you ran them, they started fresh with no memory of what happened before. Variables change that.
They let your programs store information and use it later. A variable is like a labeled box where you put data. You give it a name, put something inside, and retrieve it whenever you need it.
By the end of this section, you'll create variables, work with different data types (numbers, text, true/false values), and do calculations. These skills are the foundation of every program you'll ever write.
