There are many things that can be multiplied: numbers, vectors, matrices, functions, equations, sets, pegs...

As an abstract operation, multiplication is the same as addition. Both are binary (i.e., defined for two elements) operations satisfying the same set of axioms:

 For example: 5 × 3 = 5 + 5 + 5 = 15
