Multiplication Notation

A dot between two numbers represents multiplication in math. For example, the expression means multiply the number by the number .


Alternative Notation

Since multiplication is a very common operation in mathematics, there are alternative, short-hand ways of expressing the operation. In elementary mathematics, the (times) symbol is often used, but then later dropped in favor of the center dot, parentheses, or implicitly represented by two variables next to each other.

Multiplication Parentheses Notation
Multiplication Parentheses

Multiplication Computing Notation
