What is an algorithm?

• Focusing on the important details and ignoring the ones we don’t need.
• Breaking a big problem into smaller, easier parts.
• This is a list of rules to follow in order to solve a problem. The steps need to be in the right order.
• Looking for things that are similar in a problem to help solve it faster.
