3. Now, add an inline equation by enclosing the equation with single dollar signs. Try this example:
```{tip}
The syntax used for creation equations is TeX, a markup language for math. It's often part of the software-system LaTeX, which allows to create full documents in this language. There's plenty of documentation online on how to use it, including graphical interfaces (for example [this one](https://latexeditor.lagrida.com/))
```
3. Now let's add another equation with an error:
```md
$$ E = m \ccdot c^2 $$
```
4. Check whether the equations renders correctly by clicking `preview`. Note that all ill-formatted equation are indicated in red, i.e. $\red{\text{\ccdot}}$
5. As an alternative you try and use the 'math directive'. This will have the same results + adds a equation number which can be used for referencing:
````md
```{math}
v = a \cdot t
```
````
6. Click on `preview` again. Note that these equations don't render. That's because the 'math directive' is a MyST feature (an extension of markdown), which is not supported by the GitHub previewer that only support markdown.

Before moving on to the next exercise, make sure you understand the following:
- What is the difference between inline and block equations?
- How do you use LaTeX formatting for different mathematical symbols?
- How do you use TeX formatting for different mathematical symbols?
- What is the purpose of using single vs. double dollar signs for equations?
- How do you troubleshoot if your equations are not rendering correctly?
