Me 2 seasong.I'n dreaming about my math test.
Very comforting :p.I think i'm gonna fail.
Thank you you two! I'm always sick away! the reason i discovered this site and was on it for so much at the beginning was because i was sick for five weeks! Had everything.:D The women in work keep threatining to put me down!:lol:
I'm thinking i wouldnt mind a tea cake! (no tea though. Diuretic:bawling: )
Sickness has its good side too, one tends to slow down on life and realise one needs to catch up. Its so nice that you came to the site, its been good for us too :D
But, do take good care of yourself :)
i will. thank you madi!:)
Isnt it strange that I said 'one tends to slow down' and then I said 'one needs to catch up.' So confusing. But you know, I dont usually think right :p :lol:
i think i understood you anyway! maybe all those latenights are starting to catch up with you.
Im think melted snow and black ice and slee dont make the best walking conditions. And if I dont hurry IM going to be late for work but IM still eting breakfast.
how in the world do i approach this math problem? gah
lets see it then drame....
The test of divisibility by 11:
"A positive integer is divisible by 11 if the sum of the digits in the odd positions mius the sum of the digits in the even positions is a multiple of 11"
Prove this statement for a 5 digit number
I have tried making formulas but nothing seems to work..:(
Do you just have to come up with a five digit number, or a formula?
(sum of odd positions) - (sum of even positions) = n
where "n" is a number that is divisible by 11, or n/11
so all you really have to do is plug in numbers so when you subtract "sum of even positions" by "sum of odd positions" the total(n) comes out to be 11,22,33,44,55,etc...
so for example my five digit number can be this:
10912
sum of odd positions: 1+9+2 = 12
sum of even positions: 0+1 = 1
12 - 1 = 11 = n
n/11 = 11/11 = 1
THank you SO MUCH ktd!! It makes much more sense now! Thank you thank you thank you!
*is thinking ktd is a really fantastic, brilliant friend*
Your welcome! Friends help each other out.
How can I return ktd's favor? hmmm, wonder if they are still missing a sock....
