Sass Numeric Operators | Preprocessors

## Sass Numeric Operators

We can perform mathematical calculations on numbers. Sass supports all basic arithmetics like addition (`+`), subtraction (`-`), multiplication (`*`), and division (`/`).

For addition and subtraction, it is important to have values with the same units (e.g., `%`, `px`).

For multiplication and division, it is crucial to have one unitless value. Sass can't calculate the division of pixels or percentages.

### Mathematical operations with variables

We can easily involve variables in the calculations if the variable has a valid value.

Let's imagine that we need to add a double margin to the item:

Select the correct statement.
