A postulate can be derived from the original conversation:
Yes, it is always worth while going back and revising the basics. I do it myself.
If you are in harder algebra try a bit prealgebra again
Have a try solving some yourself, here: http://www.mathsisfun.com/worksheets/pr … p;ID=20709
Algebra is using of variables like x,y,z etc to solve mathematical problems.

You have both been of great help, and I'm so greatful. To MathIsFun: That was the
My favourite is the one with the square made up of a slightly smaller square and 4 rightangled triangles. It's easily the easiest one to understand that I've found so far.
Only because I saw the symmetry  more luck than good management!
I am extremely annoyed by the easiness of your method and hence the complete pointlessness of mine.
Another way to look at it is:
