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.

Mathtoid:

ELEVEN PLUS TWO = TWELVE PLUS ONE = 13

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