Essential Questions: What are integers and what are their purpose?

When you subtract two positive numbers (numbers larger than zero), it is possible to get an answer of zero. Zero is neither positive nor a negative number.

Integers are a group of numbers that include positive numbers, negative numbers and zero. Integers have no upper bound or lower bound which means that range from negative infinity to positive infinity.

Negative integers are numbers that are less than zero. Positive integers are numbers that are greater than zero.

Real World Examples Sports – Gain and lose yards in a football game Weather – Above and below zero Geography – Above and below sea level Money – deposit and withdraw money

The number line is a line labeled with the integers. Numbers to the right of zero are positive, and numbers to the left of zero are negative.
