## A list of common algebraic operators in LaTeX

This is video #14 in a series of twenty one by Dr Vincent Knight of Cardiff University.

Here we present a list of algebraic operators commonly used in LaTeX equations. These include

$a+b$
$a-b$
$-a$
$a\cdot b$
$a\times b$
$a/b$
${a\over b}$
$\frac{a}{b}$


The final two in the list both show how to write fractions in LaTeX; the use of \frac is more widely used than \over. In the next two videos we'll see how to include integrals and matrices.

To try this for yourself, the example from the video is provided as a template. Simply open the 'Operators' example (opens in a new tab/window), and get started using the free online writeLaTeX editor.
