The term "product" refers to the result of one or more multiplications. For example, the mathematical statement a×b = c would be read "a times b equals c, " where a is called the multiplier, b the multiplicand and c is their product. In addition, a and b are factors of c. More generally, it is possible to take the product of many different kinds of mathematical objects, including those that are not numbers. For example, the product of two sets is given by the Cartesian product. In topology, the product of spaces can be defined by using the product topology. The product of two groups, vector spaces, or modules is given by the direct product. In category theory, the product of objects is given using the category product.
