when you add a positive and a negative number, you subtract their absolute values and use the sign of the number having the greater absolute value

abs value(-3 1/2) + abs value(+5)=5-(3 1/2)=1 1/2

the positive number 5 has the greater absolute value so the answer is +1 1/2 or simply 1 1/2

remember, absolute value is never negative, only positive or zero
