It is so strange that we can find both words (Aluminium & Aluminum) in the dictionary.

Finally, I found that Aluminium is used in U.K. while Aluminum is used in U.S. Just like 'colour' and 'color'. We just keep in mind that some U.S. words are shorter than U.K.

• There are three people going to rent a hotel room, the room rate is $30
• After their discussion, they are willing to pay, each people pays $10
• They paid $30 for the rent.
• However, the hotel actually has a $5 discount on each room rental. The staff is greedy to take the $5.
• Finally, the manager knows it and urges the staff to return $5 to them.
• Once again, the staff is very greedy that he just return a total $3 to those 3 people.
• That is, each people only has to pay $9 ($10 - $1) for the rent.

Total is: $9 x 3 + $2 = $29

Where's the $1 gone?
