Magic tricks lay at the heart of the art of magic and a performance, so the amount of work and practice that magicians put into their tricks is understandable. All magic is based on a set of principles that have been designed and used for centuries and when performing magic tricks magicians rely on sleight of hand to pull them off in front of crowds. For this reason, the fact that there is a trick to every piece of magic, a magician's performance has come to be named a set of magic tricks instead of just magic.
We know that there is an explanation behind all magic tricks, but those explanations are not always obvious to viewers. Keeping the trick concealed and unapparent to the crowd is the main job of the magician, if his audience were to figure out or notice the trick, all element of surprise would be lost and the magic show is over. For this reason, there is also an unspoken code among magicians regarding the basic principles and sleight of hand that is used. In keeping these basic practices secret, magicians can perform their tricks confident that their audience will not be able to easily guess at how the tricks are being accomplished.
Even though all magicians base their magic tricks off the same set of principles and use some degree of sleight of hand, creating their own tricks and performance is integral to the art of a magician. Over time, magicians will create signature magic tricks or become better in one form of magic over the others. Each type of magic trick falls into a different category, and magicians may work more towards performing one than another. A vanishing and a production are two of the oldest types of magic illusions and the most commonly performed tricks. Other illusions like, predictions and penetrations are not considered by everyone to be an entire type of illusion on their own for one or several reasons.
The many schools of magic and magic tricks that are performed are generally past down from magician to magician, but no magician will share his secrets with someone who refuses to take a magician's oath. Only then can someone train to learn the magic tricks of other magicians and learn enough sleight of hand to be able to create their own routines. The sharing of techniques and execution by all magicians regardless of skill level is important to the continued life of the trade. For this reason, not only do magicians pass on their knowledge to those that will work with them, but they form clubs or groups of trusted magicians in order to share information with each other.
While the presentation of magic can be in any form, from the theatrical to the serious to the horrific, the magic tricks are the root of the show. Without good knowledge of the principles of magic and hard work to master sleight of hand, convincing magic tricks are just not possible.
How To Magic Tricks
In case you don't know, the divisibility of a number refers to whether a number can be evenly divided by another. For example, 24 is divisible by 2 but 13 is not as it leaves a remainder.
Here are some mental arithmetic magic tricks I have found that you can use to impress your friends, your colleagues, your teachers, .. .
1. if a number is divisible by 3 then so are the numbers based on mixing up the digits of the original number. For example, consider 123 which is divisible by 3. Then 132, 213, 231, 312 and 321 (which are obtained by mixing up the digits 1, 2 and 3 that make up 123) are all divisible by 3. This is called a permutation of the digits of a number. Check it for yourself!
2. to make up a number that is divisible by 4, make up a numberr and tag on the end any 2 digit number divisible by 4. For example, I make up the number 111111111, and now I tag 16 (which is divisible by 4) on the end to get 11111111116. This number is divisible by 4. Check it for yourself!
An interesting trick follows on from this one. The following numbers are all divisible by 4: 116, 1116, 11116, 111116, and so on .. . Not what you would expect!
3. if a number is divisible by 6, then any permutations of its digits will give you a new number divisible by 6 as long as the last digit is even. For example, 1272 is divisible by 6. Permutations of its digits while keeping the last digit even gives me 2172, 2712, 1722, 7122, 7212 which are all divisible by 6. Check it for yourself!
4. to make up a number that is divisible by 8, the process is similar to point 2. above. Make up a number and tag on the end any 3 digit number divisible by 8. For example, I make up the number 777777, and now I tag 016 (which is divisible by 8) on the end to get 777777016. This number is divisible by 8. Check it for yourself!
Another interesting trick follows on from this one. The following numbers are all divisible by 8: 7016, 77016, 777016, and so on .. . Again, not what you would expect!
5. if a number is divisible by 9 then so are the numbers based on mixing up the digits of the original number. For example, consider 189 which is divisible by 9. Then so are 198, 819, 891, 918 and 981. Check it for yourself!
6. if a number is divisible by 11, then permutations of its odd digits and/or its even digits will give you a new number also divisible by 11. For example, consider 154 which is divisible by 11. Then so is 451 (obtained by swapping its first and third digits). Another example, consider 1122 which is divisible by 11. Then so is 1221 (obtained by swapping its second and fourth digits). Check it for yourself!
7. if a number is divisible by 12, then any permutations of its digits (except for the last 2) will give you new numbers also divisible by 12. For example, 14652 is divisible by 12. Then so are 16452, 41652, 46152, 61452 and 64152. Check it for yourself!
You have to agree that such tricks do look like arithmetic magic which you can do in your head. Hence the title of this article being 'mental arithmetic magic'. In case you are wondering 'why is it so?' The answer lies in the test that determines whether a number is divisible by another.
