Lesson
• Integers with operations:
• SPI 0706.2.5 Solve contextual problems
that involve operations with integers.
Additive Inverses (opposites)
What you add to a number to get zero.
The negative of a number.
Example:
The additive inverse of -5 is 5, because -5 + 5 = 0.
The additive inverse of +5 is -5 as well.
