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

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

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

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

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