1 Integers

2 Negative & Positive Whole Numbers

3 Zero Principle + = zero Adding Integers Using the Zero Principle
Zero Principle: +2 and -2 are opposite integers So, they cancel each other out + = zero - + - +

4 Adding Integers - Zero Principle
Example: (+3) + (-2) = (+1) + + - + - +

5 Adding Integers - Zero Principle
Example: (+8) + (-5) = (+3)

6 Adding Integers - Zero Principle
Example: (- 7) + (+4) = (-3)

7 Snake Game (+3) + (-2) + (-7) + (+11) = ( )
(+3) + (-2) + (-7) + (+11) = ( ) (-5) + (-3) + (+6) + (+1) + (-10) = ( )
