5 Digit Number Magic

5 Digit number Difference magic

Slide2

Write a five digit number. 

Reverse it. 

Subtract (smaller from the bigger) 

score out any one of five digits in the difference. 

Tell the remaining digits in any order. 

The scored out digit is given immediately.

How…???

Slide 3

For Example:

Write a 5 digit number -- 59264

Reverse it --- 46295

Subtract it from bigger - 12969

Let the digit scored out be 6.

The remaining digits are 1, 2, 9, 9

Tell the remaining digits in any order. 

The scored out digit is given immediately. 

It is 6

How…???

Slide4

How…???

Slide5

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 ]

Slide6

For Example:

Write a 5 digit number -- 34506

Reverse it --- 60543

Subtract it from bigger - 26037

Let the digit scored out be 0.

The remaining digits are 2, 6, 3, 7

Tell the remaining digits in any order. 

The scored out digit is given immediately. 

It is 0

How…???

Slide7

Find the total of 2, 6, 3 and 7. 

It is 18.

If we add 0, it is divisible by 9. Hence the scored out digit is 0.

[ if 0 or 9 is scored out, we can say either 0 or 9 ]

Amazing 
Repeated subtraction 6174!

Slide1

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?

Mysterious count

 

Fun with Mathematics



1. The mysterious count- trick

2. Match stick count – odd or even game

3. opposite face of the dice

Slide2

Take a watch and ask someone to think of one of the hours on the dial 

then you take a pencil and start tapping the various hours on the dial. 

The person who is thinking of the hour should count the number of taps starting next from the (number) or hour he is thinking of.

When his count reaches 21 he should shout stop.

Now I will tell the hour which he is thinking of.

Slide 3

Take a watch and ask someone to think of one of the hours on the dial -- 8

then you take a pencil and start tapping the various hours on the dial. 

The person who is thinking of the hour should count the number of taps starting next from the (number) or hour he is thinking of.

 

When his count reaches 21 he should shout stop.

Now I will tell the hour which he is thinking of

It is 8

Slide4

Take a watch and ask someone to think of one of the hours on the dial -- 8

then you take a pencil and start tapping the various hours on the dial. 

The person who is thinking of the hour should count the number of taps starting next from the (number) or hour he is thinking of.

 

When his count reaches 21 he should shout stop.

Now I will tell the hour which he is thinking of

It is 8

Slide5

Take a watch and ask someone to think of one of the hours on the dial -- 5

then you take a pencil and start tapping the various hours on the dial. 

The person who is thinking of the hour should count the number of taps starting next from the (number) or hour he is thinking of.

 

When his count reaches 21 he should shout stop.

Now I will tell the hour which he is thinking of

It is 5

Slide6

First 8 taps any random order 

but the 9th tap should fall on the hour 12

            10th tap should fall on the hour 11 

            11th tap should fall on the hour 10 in an anti-clockwise

When he says stop -- He thought the hour of

If he thinks 12 then 12 + 9th  tap  you will get answer

If he thinks 11 then 11 + 10th tap

If he thinks 10, then 10 + 11th 

If he thinks 9 then 9 + 12th  tap 

If he thinks 8 then 8 + 13th tap

If he thinks 7, then 7 + 14th tap you will get answer

If he thinks 6 then 6 + 15th  tap 

If he thinks 5 then 5 + 16th tap

If he thinks 4, then 4 + 17th tap you will get answer

If he thinks 3 then 3 + 18th  tap 

If he thinks 2 then 2 + 19th tap

If he thinks 1, then 1 + 20th tap you will get answer

Slide7

Take 20 match boxes.

You take few match sticks ask another to take few match sticks

If he has taken odd number of match, add your match sticks that total come to an even number.

 If he has taken even number of match, add your match sticks that total come to an odd number.

Play a game & enjoy

Slide8

Your friends match stick count is odd so to make even how much you are  going to give to him?

That is 

5 + 1 = 6 (even);

 5 + 2 = 7 (odd); 

5 + 3 = 8 (even)

5 + 4 = 9 ( odd); 

5 + 5 = 10 ( even)

Now you take some Match sticks Ask your friend to make compensate with his match sticks.

Carry on to play the game and learn Odd & Even numbers

conclusion

Odd + odd = even

Odd + even = odd

Slide 9

Dice are special number cubes for which the following rule applies:

You  can  make  a  simple  number  cube  by  cutting,  folding  and  gluing Card board. 

This can be done in many ways. 

In the figure below you can see

 four cuttings that can be used to make cubes, with dots on the sides.

Which of the following shapes can be folded together to form a cube that obeys the rule that the sum  of opposite faces is 7? 

Note :

 The total number of dots on two opposite faces is always seven

Slide 10

Which of the following shapes can be folded together to form a cube that obeys the rule that the sum  of opposite faces is 7? 

Note : 

The total number of dots on two opposite faces is always seven 

Answer : 

ii & iii only satisfies the rule {1+6; 2+5;3+4}

My favourite subject is Maths

My favourite subject is Maths as I love to play with numbers and solve mathematical problems.

Maths gives me a lot of satisfaction and boosts my energy and thinking capacity while studying.

I love the number game and can solve problems for hours at a stretch without getting bored.

My Maths teacher also teaches us various tricks to solve mathematical sums accurately and with speed.

The best part about Maths is that I don’t need to memorise or mug up everything, like a parrot.

Maths is a very interesting subject and does not require retaining a lot of information in my mind.

Among all arithmetical exercises, I love solving addition, subtraction, multiplication and division problems.

The more I practice, the better I become at solving various arithmetical questions.

It is a captivating subject and plays an important role in our daily lives.

Finally, Maths is also a scoring subject and with proper practice, it becomes easier to score good marks in it.
