This edition is Fun with Numbers.

1. Look at the end result and how it goes up and down like a wave

• 111111111 x 111111111 = 12345678987654321

2. Arrange  all the digits from 1 – 9 in ascending order to total up to 100

• 12 + 3 – 4 + 5 + 67 + 8 + 9 = 100

3.  Here is another set of symmetrical numbers

• 1 x 8 + 1 = 9
• 12 x 8 + 2 = 98
• 123 x 8 + 3 = 987
• 1234 x 8 + 4 = 9876
• 12345 x 8 + 5 = 98765
• 123456 x 8 + 6 = 987654
• 1234567 x 8 + 7 = 9876543
• 12345678 x 8 + 8 = 98765432
• 123456789 x 8 + 9 = 987654321

 

4. The number 142857 is rather special. When you multiply it with 1 to 6 the digits found in the answer stay the same, just in a different order. Check it out:

1 x 142857 = 142857

2 x 142857 = 285714

3 x 142857 = 428571

4 x 142857 = 571428

5 x 142857 = 714285

6 x 142857 = 857142

What happens when you multiply it by 7 ? You get another rather special number:
7 x 142857 = 999999

And it doesn’t stop there:

142 + 857 = 999

14 + 28 + 57 = 99

142857 x 142857 = 20408122449

20408 + 122449 = 142857
 That’s one amazing number!

7. What is unique about 8549176320 ?

Each digit when written in words progressively moves up the alphabet list – Eight is E and Zero is Z.

 

8. How many squares are there on a chess board … ?

Its not 64 – There are a total of 204 squares on a chess board, including all sizes from 1 x 1 up to 8 x 8.

9. There were 100 chocolates in a box. The box was passed down along a row of people. The first person took one chocolate. Each person down the row took one more chocolates than the person before, until the box was empty. What is the largest number of people that could have been in the row?

Solution:

The longest line of people you can have is thirteen, with the last person taking all the remaining chocolates. There are not enough chocolates for a fourteenth person, because they would have to take 14 chocolates (after the previous person had taken 13) and there would be only 9 left.

10. And Finally  the last question for the day – why is 9 called the Indestructible number

9 * 1 = 9

9 * 2 = 18 , 1 + 8 = 9

9 * 3 = 27 , 2 + 7 = 9

9 * 4 = 36 , 3 + 6 = 9

9 * 5 = 45 , 4 + 5 = 9

9 * 6 = 54 , 5 + 4 = 9

9 * 7 = 63 , 6 + 3 = 9

9 * 8 = 72 , 7 + 2 = 9

9 * 9 = 81 , 8 + 1 = 9

9 * 10 = 90 , 9 +0 = 9
