2.1 Integers & Absolute Value 2.2 Adding Integers.

 Two Rules: 1. To add numbers with the same sign, ADD the absolute values and the answer has the same sign as the original numbers.  EXAMPLE:

ADDING AND SUBTRACTING POSITIVE AND NEGATIVE INTEGERS.

Adding Integers. Adding Integers with the Same Sign Add the absolute values. The sum will have the same sign as the addends. Example 1 Find –2 + (-3)

ADDING INTEGERS Positive + Positive = Positive Positive + Positive = Positive ( +3) + (+2) = +5 ( +3) + (+2) = +5 When a number is positive, you do not.

Adding and Subtracting Integers To add integers with the same sign, add their absolute values and then change the sign to the sign of the addends. Positive.

Integer Operations. 1) What’s the rule for adding integers? *If both addends are Positive: - Add together and the sum is positive (Ex = 12) *If.

Ex: -8+(-5) = -13

Different Signs Subtract and keep the sign of the larger number

Ex :

5 + (-10) = -5

Additive Inverse/ Opposites Two numbers whose distance from 0 are the same. Example: 3 and -3

Additive Inverse Property The sum of an integer and its additive inverse (opposite) is 0 Examples 6 + (-6) = =0
