Very annoying math brainer.

Hello everyone

I have a very annoying math brainer, that my friend told me. I have been thinking a lot about it, but just can't figure it out.

Here' the puzzle: 3 people bought a house for 30 million, making it 10 million per person. Before buying the house the salesman reduced the price with 5 million. He gave 1 million to each person, but wanted to keep 2 million of them for himself. Now every person is paying 10 - 1 = 9 million. 9 * 3 + the 2 million = 29 million, but where's the missing million?

This is obviously a very hard puzzle and nobody I know can find the soloution. Can you?

Thanks in advance...
