No guest! That answer is not 18, and you know it could not possibly be such a large number!

Think of the word as three spaces:

______ _______ _______

Now, each value on top of the spaces is how many options we can choose from:

3 3 3

______ _______ _______

Now, multiply:

3 * 3 * 3

There! **27****.**

**How could that possibly be 18? Last time I checked, 18 did not equal 27...**

**Still don't believe me? How many more can you find? Oh, so you found another one? Let me hear. ABCDEFGH? Lovely, maybe I forgot about that one....**
