Number of Siblings Magic

*With Love from the land of Ramanujan*

*With the help of mathematics I will predict how many siblings you have....* Try it. You will have a hard time believing it.

1. First, count the number of your brothers in your mind.

2. Add 2 to that number.

3. Now multiply the resulting number with 2.

4. Add 1 to it.

5. Then multiply it by 5.

6. Add the number of your sisters to it.

7. Deduct 25 from the in resulting number.

8. Now you will get a number with two digits. The first digit represents the number of brothers while the second represents the number of sisters.

*Shocked??..*

 Word Anthakshari

FUN WITH MATHEMATICS

WORD Anthakshari – 

START the WORD with previous word’s END LETTER

USING MATHEMATICAL TERMS ONLY

Rule: mathematical terms onlyaim : learninG mathematical terms

How to play:

First anyone start with one mathematical term 

for example CIRCLE

The last letter is ‘ e ‘. so,

Second one tell the word which should start with E

For example  Even 

 next one start with ‘ N’  Number

Next one start with letter “R”

Like that the games will go on……

If one doesn’t know the word then pass the level to next person

Number of Players : min 2 or more

Ramanujam Number

Professor Hardy writes, " I remember going to see him once when Ramanujam was lying ill in Putney. I had ridden in taxi-cab No.1729 and remarked that number seemed to me rather a dull one, and that it was not an unfavourable omen. 'No", he replied," it is a very interesting number". it is the smallest number expressible as a sum of 2 cubes in 2 different ways.

9³ + 10³ = 1³ + 12³ where

9³ + 10³ = 1000 + 729 = 1729

1³ + 12³ = 1728 + 1 = 1729

Hence, it is known as Ramanujam Number.

An amazing number 65!

We have leamt about the great Mathematiolan Ramanujam's number, 1729.

We ask, is there a smallest natural number which can be expressed as a sum of two squares in two different ways?

yes, There is!

It is 65.

65 = 1² +8²

65 = 4²+7²

1 is a cubic number, 8 is a cube number.

That is 65 = 1³ + 4³

Again, 1 is a square number and 4 is also a square number.

Hence, 65 is the sum of cubes of two square numbers.

Another beautitul property! 

65 + 56 = 121 =  11²

65 - 56 = 9 = 3²

Try to make every number your friend as Mathematician Ramanujan did.

Divisibility test for 2

Divisibility test for 2 is used in Table-Tennis game,

 "After each 2 points have been scored,

the receiving player shall become the serving player and so on until the end of the game-

rule book

Activity1

(1) Take a 4 digit number. (All digits different)

(2) Arrange its digits in descending order. (a)

(3) Arrange its digits in ascending order. (b)

(4) Find (a)-(b).

(5) Repeat the process.

What do you see?

(1) 9265 

(2) 9652 

(3) 2569 

(4) 9652-2569 = 7083

Repetition 

(8730, 0378, 8352),

 (8532-2358 = 6174),

(7641 - 1467 = 6174!)

Activity2

Write a five digit number. 

Reverse it. 

Subtract (smaller from the bigger)

 score out any one or five digits in the difference. Tell the remaining digits in any order. TE

scored out digit is given immediately.

Example.

     59264

(-) 46295

      12969

Let the digit scored out be 6.

The remaining digits are 1, 2, 9, 9.

Find the total of 1, 2, 9 and 9. It is 21.

If we add 6, it is divisible by 9. Hence the scored out digit is 6.

{ if 0 or 9 is scored out, we can say either 0 or 9}

Activity3

Palindrome squares

Find the Square of 836.

It is 698896.

A Palindrome square - ( Reads left and right the same number).

Activity 4

Palindrome cubes.

11³ = 1331 = 11 x 11 x 11

101³ = 1030301 = 101 x 101 x 101

111³ = 1367631 = 111 x 111 x 111

11011³ = 1334996994331 = 11011 x 11011 x 11011

Activity5

All the five squares read alike across and downwards,

	7	9	5	2	4	= 282²
309²	9	5	4	8	1
	5	4	7	5	6	=234²
169²	2	8	5	6	1
	4	1	6	1	6	=204²
