Answer 1

If you add two negative integers, what will the sign on the sum be? Explain.

the sign will be negative

For example : (-2) + (-5) = -7

another example: (-13) + (-24) = -27

If you add two integers with different signs, how can you tell whether the sum will be positive, negative, or zero?

If the integers with different signs:

1. the sum will be positive if the positive number > the negative number

for example: (-5) + 9 = 4

2. the sum will be zero if they are equal (with out considering he signs)

for example: (-14) + 14 = 0 {not 14 = 14, with out considering the signs}

3. the sum will be negative when ( with out considering the signs) the value of the digits of the negative number > the positive number

for example: (-39) + (15) = -24

note: 39 > 15
