Got this in an email too.

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

---------------------------------------------------------

1 x 9 + 2 = 11
12 x 9 + 3 = 111
123 x 9 + 4 = 1111
1234 x 9 + 5 = 11111
12345 x 9 + 6 = 111111
123456 x 9 + 7 = 1111111
1234567 x 9 + 8 = 11111111
12345678 x 9 + 9 = 111111111
123456789 x 9 +10= 1111111111
---------------------------------------------------------------

9 x 9 + 7 = 88
98 x 9 + 6 = 888
987 x 9 + 5 = 8888
9876 x 9 + 4 = 88888
98765 x 9 + 3 = 888888
987654 x 9 + 2 = 8888888
9876543 x 9 + 1 = 88888888
98765432 x 9 + 0 = 888888888
987654321 x 9 - 1 = 8888888888
9876543210 x 9 - 2 = 88888888888

Brilliant, isn't it?

---------------------------------------------------------
And look at this symmetry:

1 x 1 = 1
11 x 11 = 121
111 x 111 = 12321
1111 x 1111 = 1234321
11111 x 11111 = 123454321
111111 x 111111 = 12345654321
1111111 x 1111111 = 1234567654321
11111111 x 11111111 = 123456787654321
111111111 x 111111111=12345678987654321

------------------------------------------------------------

Now, take a look at this..

What equals 100% in life?

Here's a little mathematical formula that might help
answer these questions:

If:
A B C D E F G H I J K L M N O
P Q R S T U V W X Y Z

Is represented as:

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15
16 17 18 19 20 21 22 23 24 25 26.

If:
H-A-R-D-W-O-R- K

8+1+18+4+23+15+18+11 = 98%

But:
K-N-O-W-L-E-D-G-E

11+14+15+23+12+5+4+7+5 = 96%

And:
A-T-T-I-T-U-D-E

1+20+20+9+20+21+4+5 = 100%

It's pretty cool eh?

One of them is wrong, can you work out which one?

Oops! never thought of doing that - would be awful it there was an error

Just my luck!!!!!

Thought I had a good one here

J-E-E-P = 36%

L-A-N-D-R-O-V-E-R = 109%

sounds about right

the hare and the turtle

invest $100, first year up 10% second year down 10%

equals how much money do you have left

or the other way around

first year lose 10% second year up 10%

Wrong. It should be: 12345678987654300

Note the changes

On my calculator 111111111 x 111111111 = 12345678987654321

**p38arover** · 19th September 2009, 10:53 AM

Excel gave that figure - several times. I should have realised the last figure must be a 1.

My calculator won't calculate it.

The Windows Calculator will - and it was right.

those number pyramids look significant because they show quirks in the decimal counting system. Shift the same values to Hex, binary or octal number systems and the patterns disappear.

The significance of these is more about our cultural propensity to use a base 10 counting system than number.

The last examples are just a bit of silliness.

substituting ordered integers for letters based on their position in the alphabet and summing the result is one thing. Ascribing the result as a fractional value of and unknown whole and applying that as a rating of the underlying meaning of the word is plainly ridiculous

heres a genuine example of the magic maths
