CSS calc() - Multiplication and Division with unit-ed values

Question

Is it possible to use calc() to multiply or divide with unit-based values (like 100%, 5px, etc).

For example I was hoping to do something like this:

Answer 1

For someone who is making a mistake like me, don't forget that you can't use sass variables in css calc function directly, for that you have to use sass calculation method

$test: 10px;

.testing{
    width: #{$test * 2};
}

or if still calc implementation is necessary

$test: 10px;

.testing{
  width: calc(50% + #{$test * 2});  // results in calc(50% - 20px)
}
