My Inheritance And All About Numbers

Hello Everyone,


Mensa Puzzles
Its me again as promised the last week. People usually inherit a lot of wealth, houses, land and some even inherit their family businesses. When it came to me, I guess I inherited a lot of logical skills from my father. He used to always encourage me in solving crosswords, trying out different puzzles including





Numbers always enthused me and I looked for them wherever I went.
My house number was 7, student ID number 23, Date of Birth 22, Basketball Jersey no. 13, soon I was surrounded by numbers wherever I went. I would rather see this as a new interest in my life, 
Numbers


Wikipedia states that as a Mathematical object used to count, label and measure. I loved the counting part the most as I believe counting is very integral part of our lives. We count our moments, coins, objects and most importantly we count our blessings 







I learnt counting mostly using my ten fingers, yes I figured that out after I knew my 1-10. 
The illustration shows how I learnt counting numbers using my fingers:

There are many types of Number System, the most notable being:

  • Real numbers. Real numbers consists of all the numbers out there. They can take on any form — fractions or whole numbers, decimal points or no decimal points. Real numbers can take value ranging from -∞ to +∞ or -Infinity to +Infinity. Symbolically they are represented as |R.
  • Natural numbers. Natural numbers are all numbers greater than zero, but don’t include fractions: 1, 2, 3, 4, 5, 6, 7, and so on into infinity. Symbolically they are represented as |N.
  • Whole numbers. Whole numbers are just all the natural numbers plus a zero: 0, 1, 2, 3, 4, 5, and so on into infinity. They act like natural numbers and are used when whole amounts (no fractions) are required. Zero can also indicate none. 
  • Integers. Integers are basically all whole numbers and their opposites. Integers can be described as being positive and negative whole numbers:  –3, –2, –1, 0, 1, 2, 3, . . Symbolically they are represented as |Z.
  • Rational numbers. Numbers which can be written in the form of a fraction are known as Rational Numbers. Symbolically they are represented as |Q.
  • Irrational numbers. Irrational numbers are the opposite of rational numbers. An irrational number cannot be written as a fraction and decimals which never end. 
  • Even numbers. An even number is one that divides evenly by two, such as 2, 4, 6, and 8.
  • Odd numbers. An odd number is one that does not divide evenly by two, such as 1, 3, 5, and 7.






    Interested readers may want to check this site: History of Numbers for more insight on the origin and usage of Numbers.
    Numbers can be seen everywhere in real life including in clocks, calendars, measuring speed, distances, weight etc. I would also recommend these 2 highly rated shows namely a) Numb3rs and b) Touch for the unlimited and profound use of numbers. Right then, its me Vijay aka Mathman signing off.
    Stay Safe everyone wherever you are.
