Lesson Briefing

"Python loves numbers. Unlike text, numbers don't need quotes — Python understands them directly. You can add, subtract, multiply, divide, and do all kinds of math. There are two main types of numbers: whole numbers called integers (like 17, 42, 1000) and decimal numbers called floats (like 3.14, 9.99, 0.5). Knowing the difference will save you from some sneaky bugs later."
