I never was, am always to be,
None ever saw me, nor ever will,
And yet I am the confidence of all
Who live and breathe on this terrestrial ball.

Math poker...

Get a deck of cards. Shuffle it, and go through it one by one, doing mental math:

Spades= addition
Clubs= subtraction
hearts= multiplication
diamonds= division

Jacks = 11
Queens= 12
Kings= 13
Aces = 1

So if I pulled the 5 of spades, then the next card was the ten of hearts, I would say in my head "5 times 10 equals 50". If I next pulled a 7 of clubs, I would in my head say "50 minus 7 equals 43". Keep going, even if it requires decimals. Don't write this down unless you are totally stuck. Do as much purely in your head as possible.

No answer on this yet, give it a shot!
