Write a general rule for adding

a. two integers with the same sign

b. two integers with different signs

c. two integers that vary in sign

General rule for adding numbers

Two integers with the same signs

=> Once 2 integers has the same sign, then add.

For example

5 + 3 = 8 (5 and 3 are both positive numbers)

-5 + (-3) = - 8 (5 and 3 are both negative number, thus we added the 2 numbers)

Two integers with different signs

=> When 2 integers has different sign, then do subtraction

For example

-5 + 3 (5 and 3 has different signs)

- 5 + 3 = 2

Two integers that vary in sign

=> When 2 integers vary in sign, then it will depend on the operator

For example

5 + (-3) (5 and 3 has different signs, but the process will vary with the operator and number sign)

When positive and negative = negative

5 - 3 = 2
