Vocabulary:
Additive Inverse
The sum of a number and its additive inverse is zero.
Integers - The set of whole numbers and their opposites {-3, -2, -1, 0, 1, 2, 3}
Long Division- Standard procedure suitable for dividing simple or complex multi-digit numbers. It breaks down a division problem into a series of easier steps
Natural Numbers
The set of numbers {1, 2, 3, 4,…}. Natural numbers can also be called counting numbers
Negative Numbers: The set of numbers less than zero.
Opposite Numbers: Two different numbers that have the same absolute value. Example: 4 and -4 are opposite numbers because both have an absolute value of 4.
Positive Numbers: The set of numbers greater than zero.
