So, I thought it would be evil not to help him. I started off with basic arithmetic put into algebraic logic.

I.E. x+5=6 or x+7=6

and then, I got to exponents.

I gave him the problem: [tex]x^{2}=9[/tex]

He asked me what the super script '2' truly meant.

Now, I have always thought of [tex]x^{2}[/tex] as a two dimensional representation of a one dimensional quantity (I.E. a one dimensional line with the length of x, and to square x is to extent it equally into the second dimension or...to make it a square). I tried to explain this to him, and that to find the value of x, you just had to think of the nine as a two dimensional quantity, and represent it as a one dimensional line.

He looked to perplexed no matter how much I tried to explain it... I tried to tell him just to think of it in terms of blocks...still nothing.

Can anyone give me a better way to explain this?
