We shall use the `amsmath`

package to experiment with a very long formula and with a system of equations:

- Start a new document on an A6 paper and load the
`amsmath`

package.\documentclass{article} \usepackage[a6paper]{geometry} \usepackage{amsmath} \begin{document}

- Use the
`multline`

environment to span a long equation over three lines. End the lines with`\\`

:\begin{multline} \sum = a + b + c + d + e \\ + f + g + h + i + j + \\ + k + l + m + n \end{multline} \end{document}

**Typeset**and look at the formula:- Now we handle a system of equations. Use the
`gather`

environment to add these equations. Again, end lines ...
