YES befriend you enemy - Then you can know what he is up to and be one step in front of him.

That is what spies do.  But I don't really think that you should be a spy :)

That's much better.  Now I am all happy and so should you be :))

Thanks for giving anon the extra point, he deserved it :))

Do you like that Titanium?  Now give that point back !!!     :)))

I gave that point, so in a way you stole/took it from me :/

Now give that point back before I take 3 OFF YOU !!

No no LaTex,

I have earned a reputation for doing things the long way - maybe you learned that from me :))

Give anon back his point Titanium, don't be mean  !    

Big smiles but still give him back his point!

Hi Titanium,

You got the same answer as anonymous did!

You just did it the L O N G way.  You must be taking lessons of me I think  LOL   :))

Good answer anon, Yours was right too Titanium :))

$What do you mean by $ 3x3x \;\;?$$   

Not quite anon, when you leave the times sign out, you must have the number first so

n times 5 = 5*n = 5n

Let me see

a dime is 10c

a quarter is 25c

and a toonie is what exactly?

We are not all yanks you know  :))
