# The `calc` function
The `calc()` function lets us perform simple calculations in CSS. We can work with addition (`+`), subtraction (`-`), multiplication (`*`), and division (`/`) operators. The most useful feature of this function is the ability to mix units. For example, we could use it to subtract pixels from the  #concept=viewport#viewport#concept#
width:

```css
main {   
   width: calc(100vh - 80px); 
}
```
In this example, the `main` element has its `height` determined by a calculation of `100vh` (viewport height percentage) minus `80px` (pixels).
