The first computers were like big machines with gears and levers. People turned cranks or moved parts to make them work, just like a giant clock. They helped do math problems, no electricity needed!
Examples
- A mechanical computer is like turning a giant clock with numbers on it to add two numbers together.
- Imagine a machine that uses wheels and levers instead of buttons and screens to do math problems.
- You could turn a handle on the side, and gears inside would count up to give you an answer.
