> 6.40237371 × 1015Actually, since there are four i's and two o's, the number of distinct permutations of the letters in "oversimplification" is 18!/(4!2!) = 133,382,785,536,000.
Since the letter of the word COMPARE are distinct, i.e. none of them repeat, then the number of different way you can arrange them is simply the number of permutations of 7 things taken 7 at a time. That is 7! or 5040.

Assume you have 6 spots shown below: _ _ _ _ _ _ In the first spot, you have 6 letters to choose from. In the second spot, you have 5 letters to choose from because you already used one. Similarly, in the remaining spots, you will have 4, 3, 2, and 1 letters to choose from. So you have 6 choices * 5 choices * 4 choices * 3 choices * 2 choices * 1 choice = 720 possibilities
