Full Answer

One example of a magic trick is as follows: The person performing the trick must say that he can predict what number the trick will end with, and then write down the number 3. The person doing the trick will then ask the spectator to think of any number. After that, the trickster will double the chosen number, add 9 to the result, subtract 3 from it, divide that figure by 9, and then subtract the remainder from the number the spectator picked to begin with. The result is always 3.

Another similar math trick is for the trickster to say he can predict what number the trick will end with, and then write down the number 2. The trickster then has the spectator think of a number from 1 to 9. The trickster multiplies the number by 3, adds 6, divides it by 3 and then subtracts the remained from the original number the spectator chose. The answer is always 2.

These are just two of many math tricks that can be used to entertain people or to get kids interested in math.
