Ground is a very easy language to learn. In this guide, you will learn how to write a simple calculator in Ground, as well as best practices (which there aren't many of, since Ground is so simple).
Note: This assumes you've read and understand the syntax.md document in this folder.
### Let's start!
Open a new file with the `.grnd` extension. Should look something like this:
```
```
(Real empty in that file.)
Let's add some code! Create a label for the start, since we'll loop back once we've calculated, and ask for the user's input:
```
@start
stdout "Calculation: "
stdin &calc
```
At the calc variable, we have whatever the user typed in. This should look something like `9+10`, `1 / 3` or who knows what else. But first we should organise this data. Let's create a loop to iterate through this input, and a counter to keep moving forward:
