Q: Take the names of the first nine elements of the periodic table: hydrogen, helium, lithium, beryllium, boron, carbon, nitrogen, oxygen and fluorine. Select one letter from each of these names in order to spell a familiar nine-letter word. Hint: It's a word used in math.Did I give this away with the reference to elementary school in the title? Well there are many terms we learn in our formative years of school, so I don't think it's too big of a giveaway. However, if it did spoil the puzzle for you, get over it. On the other hand, if you want another clue, look to a puzzle we had in August.
Edit: The puzzle in question was from August 2008 where the answer was FRACTION/RATIO. This week's hint was "get over it..."
