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…
Yesterday was the birth anniversary of the famous French Mathematician Blaise Pascal(18-6-1623 to 19 -8-1662). He is a child prodigy with no formal education.
He invented the mechanical calculator at a very young age.
He is the first person who proposed the idea of public transportation in 1662 in France. He introduced the seven horse drawn carriage routes for the public. They are called as the “Five-Penny Coaches,” or “Carosses à Cinq Sous”.
In science, his focus was mainly on fluid dynamics.
The following video explains his other achievements
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 .
We know to construct the magic square of odd order, constructing the even order magic square is little tricky, we solve this by dividing the even numbers into doubly even and singly even. Let us first see about the doubly-even here, because singly-even comprises odd and doubly-even magic square constructing methods.
The following video will brief you about building the doubly-even magic squares.
Magic square – It is a square matrix, i.e., it has equal number of rows and columns. The sum of the numbers in any rows, columns and diagonals is always the same.
Creating magic squares are very easy if we follow certain rules, They are clearly explained with an example in the following video.
Happy New year!!!
