integer

Integers are the set of all positive whole numbers, all negative whole numbers, and zero.

                         { . . . -6, -5, -4, -3, -2, -1, 0, 1, 2, 3, 4, 5, 6, . . . }

Examples of INTEGERS are:
          -25 degrees Fahrenheit
           A profit of $ 500
           A loss of 5 yards
           A growth of 2 inches

Two integers are said to be opposites if they are on opposite sides of zero and equal distance for zero.

Examples of opposites
-5 and 5 are opposites because they are on opposite sides of zero and each is just 5 units from zero on the number line

The absolute value of any number is the distance that number is away from zero.

Since we only measurse distance using positive number, tha absolute value of any number will always be a positive number.

The symbol for absolute value is two straight vertical lines on either side of our number.       |   |
Lets call our number x. Therefore we write the absolute value of x as | x |

Examples of absolute value
         1.   | -5 | = 5    because -5 is a distance of 5 units from zero

         2.   | 5 | = 5     because 5 is also a distance of 5 units form zero
