| Introduction “Zero” is a number which, when added to any number, leaves the latter unchanged. The symbol for the number zero is "0". The word zero comes originally from the Hindi “sunya” which means ‘empty’, and travelled through Arabic (sifr), Latin (zephirum), eventually to become the English zero. Zero is also used as a placeholder in place value systems as a digit. It came into existence around 200 A.D. and it was the Indians who developed the use of zero. Indians were the first to recognize a mathematical representation of concept of no quantity. If there are zero things, there are not any things. There are none. Zero - a special number In mathematics, zero is a special number for the following reasons:
Symbolically it is represented as: 7 + 0 = 7.
Symbolically it is represented as: 4 – 0 = 4.
Symbolically it is represented as: 5 x 0 = 0.
Some other properties about zero
Uses of Zero in Mathematics
Magical number using zero Using six 0’s, we can get a magical number 48. i.e., (0!+ 0!+ 0!+ 0!)! x (0!+ 0!) = (1+1+1+1)! x (1+1) because 0! = 1. = 4! x 2 = 4 x 3 x 2 x 1 x 2 because 4! is 4 x 3 x 2 x 1 = 48 Applications
Conclusion As we discussed about zero on various aspects, one thing is certain that it plays a pivotal role in mathematics as well as other fields. Some problems cannot be solved in mathematics without zero. It plays a role of additive identity in integers, real numbers and many other algebraic functions.
