Loosely speaking, an algorithm is a step by step recipe of solving a problem.

Algorithms in mathematics are ubiquitous. Can you calculate 123 + 23? Yes, you can do so because you learnt an algorithm to do so in primary school.

Algorithms are a lot of fun. An interesting (and very approachable) book on algorithms is "Algorithms Unlocked" by Thomas Cormen.

What did you not understand?

An algorithm is an effective method that can be expressed within a finite amount of space and time[1] and in a well-defined formal language[2] for calculating a function.[3] Starting from an initial state and initial input (perhaps empty),[4] the instructions describe a computation that, when executed, proceeds through a finite[5] number of well-defined successive states, eventually producing "output"[6] and terminating at a final ending state. The transition from one state to the next is not necessarily deterministic; some algorithms, known as randomized algorithms, incorporate random input.

That is a lot of fancy talk, I like to think that an algorithm is like a recipe.

The use of it in math? Well, the steps you take to solve an equation or to get a GCD might be considered an algorithm.

If you think you can handle it then go here:
