# More Beauty In Math

It has been a while since we shared some fun with math in Science Club.  WIth nothing up our sleeves we proceed with some mathemagics.  As in three earlier sessions (#1 and #2 and #3) we use the operations of multiplication and addition to build a fascinating sequence.

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

On occasion one might be a lonely number but we have demonstrated methods to form phalanxes of ones which are hardly lonely.

One is the Loneliest Number

Mathtoid:

ELEVEN PLUS TWO = TWELVE PLUS ONE = 13

But did you realize that ELEVEN PLUS TWO is an anagram of TWELVE PLUS ONE

We are going to do a little math in Science Club today – actually some mathemagics.  In two previous sessions (#1 and #2) we used the operations of multiplication and addition to build some remarkable sequences.  Today we shall do another.

Try this:

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

There we are,  You can say what you like about us but you have to admit that, at least in numbers, we are very well rounded at the School Of Hard Rocks.

The last time we toyed with numbers, we admired the symmetric array produced by massively multiplying bunches of ones (see post 20120409).  Today we operate on an ascending sequence to develope a descending pattern.  Everything is really going the right way – multiplying and adding do indeed give us larger numbers each time but the digits roll off in a delightful way.  Maybe the government could use this technique to make our collective debt seem less frightening.

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
