Opposite numbers: Numbers that are the same distance from zero Can you think of some numbers that would be the same distance from zero?

Every number has an opposite NumberOpposite I have $5 #_____ 10 feet below sea level #______ 7° below freezing #_____ 20 yard gain #_____

Opposite numbers are additive inverses. What do you think this means?

additive inverses When I add these numbers together, the result will always be zero. a + -a = 0 A positive will always cancel out a negative! Example: You earn a dollar. You owe a dollar. Result: You have no money = ZERO

AdditiveInverseResult additive inverses Give 3 naked number examples and 2 real life examples of additive inverses.
