# Multiplication Notation

A dot between two numbers denotes multiplication in mathematics.

## Examples

1. 5 multiplied by 6 can be expressed as 5 groups of 6.

2. 5 multiplied by 6 is 30.

1. Four multiplied by three is the same as four groups of three.

2. Four multiplied by three is equal to twelve.

1. Two multiplied by seven is the same as two groups of seven.

2. Two multiplied by seven is fourteen.

## 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

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

Multiplication Variables

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

Multiplication Computing

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