We look at the signs of numbers when we need to combine them. We subtract only if numbers have different signs, otherwise we add them. So that, if we have in an expression several positive and negative numbers, we prefer to group numbers with the same sign and add them in order to subtract just once. While with fractions we like to group fractions with the same denominator first, and after that we can combine all fractions by finding their LCD.
