# Multiplication Variables Notation

In mathematics when two variables are next to each other the implied operation is multiplication. This makes many equations and formulas more simple.

## 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.

A dot between two numbers denotes multiplication in mathematics.

Two expressions placed next to eachother and separated by parenthesis are assumed to be multiplied together.

When entering an expression in a computer multiplication is represented using the asterisk symbol.

## Concept

Multiplication is a basic arithmetic operation performed on two numbers. Multiplying a number by another number is the same as taking n groups of the other number.
