ELI5: What is algorithm?

Context: cooking 75 views Jan 31, 2026 1 min read

Imagine you want to bake a yummy chocolate chip cookie. A algorithm is just like a recipe!

It's a set of very clear, step-by-step instructions that tells you exactly what to do to get the perfect cookie.

Think of it this way:

  • Ingredients are like the input for your algorithm. You need flour, sugar, chocolate chips, and so on.
  • The recipe steps are the actual instructions. For example:
1. Mix the butter and sugar. 2. Add the egg and vanilla. 3. Mix in the flour and baking soda. 4. Stir in the chocolate chips. 5. Drop spoonfuls onto a baking sheet. 6. Bake for 10 minutes.
  • The baked cookie is the output – what you get at the end!
If you follow the recipe (the algorithm) exactly, every time you bake, you'll get a cookie that looks and tastes pretty much the same. If you skip a step, or add too much of one ingredient, your cookie might not turn out so well.

So, an algorithm is just a detailed set of instructions that you follow to achieve a specific goal, like baking a cookie! It needs to be clear and precise so anyone can follow it and get the same result.
