Fingers and Toes
Two of the world's best mathematicians were given the following problem:
If you take all the fingers on one hand and multiply it with all the fingers on your other hand, then subtract the number of toes on both of your feet, what number would you get?
If both mathematicians had all of their digits, and were 100% sure that they did all of their math correctly, how come one of them came up with an answer that was nearly 3 times that of the other?

Answer
One of the mathematicians counted each of the digits on his hand as a finger. 5 times 5 equals 25. 25 - 10 (the number of toes he has) = 15.The other mathematician counted each of his fingers; 4. 4 times 4 equals 16. 16 - 10 = 6.
Some people mistakenly count the thumb as a finger, which is what the first mathematician did.
