Henry Dudeney, a self taught Mathematician known for his puzzles, first noted the existence of these numbers while framing one of his puzzles.
What’s so special about these numbers?
What is the pattern followed behind the construction of these numbers?
Yes! There is a very interesting pattern behind these numbers.
Let’s check that pattern in the following video.
This math trick helps the kids think about the patterns behind the calculation and their amazing fixed answer.
Mastering this concept will make them believe that they are a tricky mathe-magician.
The following video will explain about the math trick behind the magic number 1089.
The mathematical proof of the above trick is as follows:
Interesting name, isn’t it?
How can a number be narcissistic?
☻When it focuses too much on itself☺.
It will represent itself even after some manipulation of its digits.
“A number is said to be narcissistic if the sum of its own digits each raised to the power of the number of digits is equal to itself”
For example:
153=13 + 53 + 33 = 153.
These numbers are also called as Armstrong numbers or plus perfect numbers.
The following video has some details about this…
A Krishnamurthi number is a number whose sum of the factorial of the digits is equal to the number itself.
A palindrome number is a number that remains the same when its digits are reversed .
Today’s date is one such example.
12-3-21, even if it is reversed, the answer will be the same .
Happy New year!!!
