2Think about making a sandwich: 1) Get bread, 2) Add filling, 3) Close it. Each step is easy on its own!
3In coding, we call this 'decomposition' — breaking a big problem into smaller, manageable pieces.
4Every app, game, and website was built this way — one small step at a time. You can build anything if you break it down!
