The lucky-number has become increasingly popular in daily life of mordern socialty. For example the number eight means big money which people like most while the number four means death.

Some people believe lucky numbers so deeply that they will afford a telephone with numbers without four and others which is bad in their mind. they argue that the lucky-number really can bring good luck and at least no evidence testify they can not.

As far as I am concerned there is no such relationship betwwen the numbers and lucky for the reason that numbers theirself are given certain meaning for the purpose of application of mathmetic. And In addition man should not depend on lucky which in their mind the numbers gives them.
