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

Hi Haley;

-3 1/2 + (+5)

The negative of 3 1/2 means that it is being subtracted.

The double positive means that it is being added. If there are a multitude of

**positive**signs, it would be added. If there is more than one**negative**sign, that would be different. If there is an odd number of negative signs, such as 1 (herein) or 3 or 5, that means the number must be subtracted. If there is an even number of negative signs, such as 2, 4 or 6, that means the number must be added.-3 1/2 + (+5)

=1 1/2

This is because

1 1/2 + 3 1/2

is

4 2/2

is

5

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