Python Prep 07: The "1+1=11" Problem & Math with Strings vs. Numbers

Why does Python sometimes think 1 + 1 is 11? In this lesson, we solve the mystery of the "String Trap" and master Arithmetic Operators.

We explore how Python handles math differently depending on whether you are using Integers, Floats, or Strings. You'll learn how to use the standard math symbols and a few "secret" string tricks that Python allows.

What we cover today:
The "1+1=11" Mystery: Understanding string concatenation vs. mathematical addition.
Arithmetic Operators: * The basics: +, -, *, /.
Working with int and float results.
String Math (The Fun Part): * + with Strings: Joining text (Concatenation).
* with Strings: Repeating text (e.g., "Ha" * 3 becomes "HaHaHa").
Fixing User Input: How to wrap your input() in a type conversion to make math actually work.
