Multiplication in Algebra


$x \cdot y$ means $x$ times $y$, or $x$ multiplied by $y$.

A binary operation on two variables.

Usually used when variables are involved (as opposed to numbers) to avoid confusion with the use of $\times$ which could be confused with the symbol $x$ when used as a variable.

It is preferred that the symbol $\cdot$ is not used in arithmetic between numbers, as it can be confused with the decimal point.

Its $\LaTeX$ code is \cdot .

Historical Note

The symbol $\cdot$ was the preferred notation of Leibniz, who criticised William Oughtred's invention of $\times$ for being too similar to the letter $x$.

Leibniz's preference $\cdot$ is now widespread.
