There is something I don't understand about algebra: It has been around for thousands of years, yet no one has ever found out what the value of "x" or "y" really is.

If you think dogs can't count, try putting three dog biscuits in your pocket and then giving tommy only two of them.

M4Math helped me a lot.

I must recommend this website for placement preparations.
