Algorithms: clear steps in order

What you will learn
By the end, you can write an algorithm: a list of clear steps, in order, that anyone (even a robot) can follow.
Ben tells his kitchen robot: "Make a jam sandwich." The robot does not move. It only understands small, exact steps in the right order. Miss one step and it spreads jam on the plate, not on the bread.

An algorithm is a list of clear steps that does a job. A recipe is an algorithm. Brushing your teeth is an algorithm. Computers follow algorithms exactly, so every step must be clear and in the right order.
- Each step is small and clear: one action per line.
- The order matters: you cannot brush before the toothpaste is on.
- A good algorithm works every time you follow it.
