# Definition of Algorithm

An algorithm is a sequence of steps you perform to complete a task like solving a problem or baking a cake.

A recipe is an example of an algorithm.

Some other examples of algorithms are the steps involved in long division, computer programs and the instructions for building a model.

Let's work through the steps of one algorithm for adding three digit numbers (without borrowing or trading):

The algorithm is as follows:

- add the units
- add the tens
- add the hundreds
- combine the three digits from steps 1-3 to give the answer.

Let's use it to add \(123\) and \(245\):

- add \(3\) and \(5\) to give \(8\)
- add \(20\) and \(40\) to give \(60\)
- add \(100\) and \(200\) to give \(300\)
- combining these three numbers together gives the answer of \(368\).
