Age of Mythology Strategy Game - Help Please  

Hello MyLotters,
I don't know if you guys have EVER heard of the game, but it's a strategy, VERY MUCH like Age of Empires, and VERY OLD game.
But, I wanted to play it, I got the 'Age of Mythology - The Titans Expansion', but alas, I forgot the Age of Mythology first game (the base the expansion runs on).

I needed to ask, can I put the expansion on Age of Mythology Demo? Else I have to go and buy that too....
