When given an algebraic expression involving subtraction why
is it best to rewrite the expression using addition before identifying the terms
is because you can consider the basic rule of operations such as the PEMDAS or
simply the MDAS in computing and calculating equations. Hence Addition comes
before Subtraction. For example given -3 + 5, you can arrange this set into a
simpler one such as 5 – 3 = 2. You aim to have a positive sum rather than a
negative value sum.
