Introduction

You have probably come across math trivia related to birthdays once a week if you are on social media – and wondered why it’s so popular.  The reason is obvious – most children show keen interest in any trivia related to their birthdays.

As adults, we may often fail to recognize how explaining any trivia related to your child’s birthday helps them integrate math into their real life situations – and not view it as just a ‘subject’.

Birthday Math Trivia

The question is: Is your child’s birthday unique?

We can attempt to answer this only in comparison to the universe your child identifies with.

For example, your son (Samit) was born on the 14th of January. Samit’s class has 40 students. What are the chances of any of Samit’s classmates sharing his birthday?

At this point, you can delve into the concepts of probability and the pigeonhole principle. If the criteria (uniqueness) is less than the universe your child identifies with, then probability comes into the picture. On the other hand, if the criteria is greater than the universe your child identifies with, the pigeonhole principle comes into the picture.

Here’s how:

Given that there are 365 days in a year and 40 students in Samit’s class, there is a 10% chance ((1/365) x 40) that another student shares his birthday. This is probability – where the universe 40 is smaller than the criteria (365 days).

However, if Samit’s school has 3000 students, what are the chances of him sharing his birthday with his schoolmates? Since the universe has changed from previous 40 (limited to his class) to 3000 (his school), chances are at least 8 other students ((1/365) x 3000) share their birthdays with Samit.

His uniqueness is, therefore, reduced as it is the function of universe you identify him with. This is the pigeonhole principle – where the universe (3000) is greater than the criteria (365 days).


Birthday Math Trick

Also we have Birthday Math Trick that spice up math class.This little math trick should make you seem like a sort of math genius.Make sure you try this trick out for yourself first, using your own birthdate.

Here's an example below...

Let's suppose someone has a birthdate of August 22, 1964.

So we want to use the format of month/day/year so this birthdate would be 08/22/64.

Notice we only used two digits for the year.

18 + 8 = 26
26 x 25 = 650
650 - 333 = 317
317 x 8 = 2536
2536 - 554 = 1982
1982 / 2 = 991
991 + 22 = 1013 
1013 x 5 = 5065
5065 + 692 = 5757
5757 x 20 = 115140
115140 + 64 = 115204
1295204 - 32940 = 82264

And there you have it....8 22 64 which is the same as August 22nd, 1964!

Try this cool birthday trick with your friends and surprise them. Hope you will have fun with them.

Frequently Asked Questions (FAQs)

Who is the father of math?

The study of mathematics as a "demonstrative discipline" begins in the 6th century BC with the Pythagoreans, who coined the term "mathematics" from the ancient Greek μάθημα (mathema), meaning "subject of instruction".

Is the number zero a number?

0 (zero) is a number, and the numerical digit used to represent that number in numerals. It fulfills a central role in mathematics as the additive identity of the integers, real numbers, and many other algebraic structures. As a digit, 0 is used as a placeholder in place value systems.
