The General rule for adding and
subtracting numbers


  1. Two integers with the same signs

Once 2 integers has the same sign, then just add
the numbers.

For example


1. 1+1 = 2


2. 2 + 5 = 7



2. Two integers with different signs
When 2 integers has different sign, then find the
difference

For example

  1. 1-1 =0
    2. 2 – 5 = -3



3. Two integers that vary in sign
When 2 integers vary in sign, then it will depend
who which number carries the largest value

For example


1.
-3 + 2 = -1


2.
2 – 1 = 1

The correct answer is:

When adding two integers with different signs, subtract the absolute values (the digits without signs) and keep the sign of the number with the larger absolute value.

Explanation:

When subtracting integers, it is helpful to think of a number line. Subtracting from a number means we start at that number and travel backward on the number line.

For example, in the problem 5-8, we begin at positive 5 and go backward 8. In doing so, we go past 0. It takes 5 units to get there, which leaves us with 3 units in the negative; this means the answer is -3.

This is the same as subtracting 8-5 and taking the negative sign.
