//
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
 
 
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=123456789 87654321

Remember the song, "12 Days of Christmas"?  How many presentss were received during those twelve days?
Look:

On the:
1st day  -   1 present (a partridge in a pear tree - I'm not going through all of 'em)
2nd day  -   2 + 1 = 3
3rd day  -   3 + 2 +1 = 6
4th day  -   4 + 3 + 2 + 1 = 10
5th day  -   5 + 4 + 3 + 2 + 1 = 15
6th day  -   6 + 5 + 4 + 3 + 2 + 1 = 21
7th day  -   7 + 6 + 5 + 4 + 3 + 2 + 1 = 28
8th day  -   8 + 7 + 6 + 5 + 4 + 3 + 2 + 1 = 36
9th day  -   9 + 8 + 7 + 6 + 5 + 4 + 3 + 2 + 1 = 45
10th day - 10 + 9 + 8 + 7 + 6 + 5 + 4 + 3 + 2 + 1 = 55
11th day - 11 + 10 + 9 + 8 + 7 + 6 + 5 + 4 + 3 + 2 + 1 = 66
12th day - 12 + 11 + 10 + 9 + 8 + 7 + 6 + 5 + 4 + 3 + 2 + 1 = 78

Sooo.. 1+3+6+10+15+21+28+36+45+55+66+78 = 364 +1 (Christmas Day) = 365, or the number of days in a year .....

Somewhere, a friend and I also figured out how much all of these things would cost, too - as soon as i find it. I'll post it.

For some other good and interesting math equations, try the "Necroscope" series by Brian Lumley - some very intriguing mathematical questions woven into the story.....

3y + 6x=18

Find the y and x intercepts, and slope.

slope= -2, y-intercept= 6, x-intercept= 3
