A is also for average. An average is the quotient of the added data set divided by the number of items in the set. It is also called the mean. [] Here's a way to calculate your grade point average!

Algebra: A branch of mathematics dealing with symbols.

==Go to this link- it has some good examples of additive inverse!http://www.coolmath.com/prealgebra/06-properties/07-properties-additive-inverse-01.htm ==

You can use addition with **4x + 7y + 6x + 3y = to solve COMBINE only the values with the same variable! 4x + 6x becomes 10x and 7y + 3y becomes 10y so the simplified version 4x + 7y + 6x + 3y is 10x +10y == ==Associative Property: When you can change the order of the problem and it will have the same product or sum. Ex: (3+4)+5=(5+4)+3 == ==Absolute Value Absolute value is the value of a positive or negative number in positive form. An example is. . . -7+9=? you find the absolute value of -7 and 9 the absolute value of -7 is 7 the absolute value of 9 is 9 then you must subtract 9 form 7 9 - 7 = 2 then you take the biggest number's sign (+ or -) and that is the sign of the answer. -7+9=2 == == **R**  == == [|�22�]           [|�30�]      ==
