LordOfTheBorg 1 Posted September 5, 2005 I was thinking last night of math thoughts, and I thought of this. I don't know if I took it from somewhere, or what.. but, here it is.. each multiple of 10 goes up by one... (10, 20, etc) Erase the 0's, and it goes up by one. Ok, now all numbers going down from 10(9,8,etc.) go up by their value minused from the bigger ten. Look: 9, 18, 27. See how it goes down by 1 from each ten? 9 is 1 away from 10, so you subtract that from the number. (It only works in multiples) more examples: 8, 16, 24, 32, 40... 7,14, 21, 28... 6, 12, 18... Sorry if you don't understand, i had it all figured out last night, but it kinda faded from my mind today. Anyways, I dont know if this is an original idea for me, or if i stole it from someone, but...yeah... Share this post Link to post Share on other sites
