Substituting means replacing one thing with another. Think of it like swapping ingredients in a recipe 🧑🍳, using a pinch hitter in baseball ⚾, or a stunt double in a movie 🎬. It involves using an alternative when the original isn't available or suitable. In math, you might substitute a variable with a number to solve an equation. In life, you might substitute a healthy snack for junk food. It's all about finding a replacement that serves a similar purpose.
