Hello, how are you? :)

In this post I tell you how to create conditional expressions and what you can do if you have multiple equations and align them at the center. Let's start!!!

## Conditional Expressions

You need to use the `cases`

instruction to define the expression

```
\begin{cases}
equation
\end{cases}
```

Produces

You can add a new file with `\\`

at the end of the line

- This must be inside a math environment like
`$ $`

,`\[ \]`

or`equation`

## Aligning Multiple Equations

We have seen many ways to write equations, but ** Just one equation** what if you want to write 5 equations, or more than 5 equations? Do we need to put each equation in

`\[\]`

it is going to be a nightmare!!There exist an environment, the `gather`

environment this centers a group of formulas on a separate line

Produces

- You can create a new line with
`\\`

- No blank lines are permitted within the environment

This is all for today.
