Sass is returning a list of negative numbers instead of subtracting them

Question

I\'m trying to do math operation with lengths:

$itemWidth: 25px;
$item2Width: 80px;

element {
    width: $itemWidth/2-$item2Width/2-5px
}

Answer 1

Wrap the calculation in parentheses. This tells SASS that the whole thing is part of a calculation.

$itemWidth: 25px;
$item2Width: 80px;

element {
    width: ($itemWidth/2-$item2Width/2-5px);
}
