## To pass the GED math test, it is important that
you know the basics of adding, subtracting, multiplying, and
dividing integers. Basic algebra review watching GED math
videos, reviewing for the GED algebra test, and practicing
problems for the GED math test will help prepare you.
Integers are the set of signed numbers.
Signed numbers include positive numbers (example the
number 9), negative numbers (example -9), and 0.
The integers are
...-8,-7,-6,-5,-4,-3,-2,-1,0,1,2,3,4,5,6...
Numbers decrease in value as you go from right to left.
0 is considered the "origin" and is neither negative or
positive. The absolute value
"|
|" is the distance from a number on a number line
to 0. Two numbers that are an equal distance from 0 are
called "opposite" numbers. An example is -3 and 3.
To find the absolute value of a number, look at the number.
If the number is positive or 0, the absolute value is that
number. If the number is negative, make the number
positive to find the absolute value. Example:
The absolute value of 6 is 6. The absolute value of -14 is
14.
| 6 | = 6 | 0 | = 0 | -2 |
=2 | -14 | =14
The symbol "-" can be used to indicate
subtraction, a negative number, or "the opposite of". |
