I am a high school drop out and its been nearly 9 years. I dropped out in my freshman year so things I learned are very fuzzy and there was a lot I didn't learn. I am currently studying for my GED and coming upon the math section I realized I know diddly about algebra. I have no clue as to where to begin. I don't know what a means or x or all the funny little symbols If some one could give me a hand with this I would greatly appreciate it Thank you

The best way really is to just work through this stuff. However, to start you off: Concerning this letter "x" We use x all the time as a sort of symbol for a number. It's nothing tricky, it just stands in for a number the same way, for example, the word "price" stands for the dollars and cents price of an item when you talk about buying several of an item. In stead of always saying "price", "length", "weight", etc., we simply abbreviate, usually with x and y, but certainly any letter is generally fair game. For example, you know that to find the area of a room, you would take the width (in feet) times the height (in feet). In terms of algebra, one might just write A = w·h or simply A = wh (mathematicians are so lazy we don't even usually write in the 'x' for multiplication, we just put a dot, or even nothing at all). Both of these are the same statement and mean exactly what I said previously in plain English. So, if A = w·h, and h = 5 and w = 4, what is A? I hope this helps a little, please tell us if this is not what you are looking for. -Nathan
