Number Line 3 - Order, Graph, and Compare Integers

An integer is any number from the set {…, -4, -3, -2, -1, 0, 1, 2, 3, 4 …} where … means continues without end

To graph an integer on the number line, do the following:
1) Draw a number line
2) Identify the location of the integer on the number line
3) Draw a dot at the location that represents that integer

Integer on the right is always greater than the integer on the left on the number line

Integers that are on the right side of zero on the number line are called positive integers

Integers that are on the left side of zero on the number line are called negative integers

An integer is any number from the set {…, -4, -3, -2, -1, 0, 1, 2, 3, 4 …} where … means continues without end

Additive Inverse or Opposite is a number which is at the same distance from zero as the original number on the number line but in the opposite direction.
For example: - 2 and + 2 are at the same distance from zero that is 2.
So, - 2 and + 2 are opposites or additive inverses

|n| is the symbol for absolute value of n, where n may be positive or negative

Absolute value is the distance of a number from zero on the number line.
For example: Distance of -5 from zero is 5.
So, |-5| = 5
