Odd Numbers

 

What are Odd Numbers? 

Odd numbers are whole numbers that cannot be divided exactly into pairs.

Odd numbers, when divided by 2, leave a remainder of 1. 

Odd numbers

1, 3, 5, 7, 9, 11, 13, 15 … are sequential odd numbers.

Odd numbers have the digits 1, 3, 5, 7 or 9 in their ones place.



Fun Facts
1. The sum of two odd numbers is always even.
2. The product of two or more odd numbers is always odd.
3. The sum of an even number of odd numbers is even, while the sum of an odd number of odd numbers is odd. For instance, the sum of the four odd numbers 9, 13, 21 and 17 is 60, while the sum of five odd numbers 7, 15, 19, 23 and 29 is 93.

INVENTION OF ZERO

 INVENTION OF ZERO The concept of zero has not always been around, however, the introduction of zero bought a lot of changes not only in math but also in the general life of people. Zero has so many different names, for example, ‘null’, ‘nil’, ‘0’ as a digit, ‘sunya’ in Sanskrit, and so on. It is fascinating how the origin of zero bought changed and now it is used as a prime digit in mathematics. Before learning about the modern zero, let’s learn about the origin of zero in India,   Origin of Zero in India The origin of zero in India came from a well-known astronomer and mathematician of his time, Aryabhatta. The well-known scientist used zero as a placeholder number. In the 5th century, Aryabhatta introduced zero in the decimal  number system  and hence, introduced it in mathematics. After Aryabhatta, Brahmagupta described rules for zero in the 7th century. The most evident proof of the origin of zero in mathematics is mentioned in the oldest manuscript of India known as the ‘Bakshali

RAMANUJAN'S INFINITE SEQUENCE OF SQUARE ROOT (NESTED RADICAL).

         INFINITE SEQUENCE OF SQUARE ROOT        INFINITE SEQUENCE :                   An infinite sequence is a list or string of discrete objects, usually numbers, that can be paired off one-to-one with the set of positive integer s {1, 2, 3, ...}. Examples of infinite sequences are  N  = (0, 1, 2, 3, ...) and  S  = (1, 1/2, 1/4, 1/8, ..., 1/2  n  , ...).  INFINITE SEQUENCE OF SQUARE ROOT: Consider,                  y = x + n                (x +n)² = n² + x(x+2n)               (x + n) = √[ n² +x(x+2n)]               (x + 2n) = √[ n² +x(x+2n)(x+3n)]               ( x + 3n) = √[ n² +x(x+2n)(x+3n)(x+4n)]               ...               ...               ...               ...               ...                x+n = √[ n² +x √ n²+(n+x) √ n² +(n+2x).... ]   Remarkably the answer is exactly 3.    We have verified the pattern holds up to 4, with the next term under the radical being 6 = √6 2 . Let’s justify why the pattern will continue. Assume the pattern holds where  n  – 2 is the coef
