Dividing 1 by 998001 gives every three digit number from 001 to 999 in order. Dividing 1 by 9801 will give every two digit number from 01 to 99 in order. Ooooooor you can type in 5318008 and show it to everyone upside down and we'll all have a laugh about it in Algebra before going back to playing drug dealer on our TI-82s (I went to high school in the 90's, kids -- we didn't have T-1000's or whatever the hell they're up to now).

Thanks to Donald, who felt obligated to include the whole joke equation that yields '55378008' in his tip and I don't blame him.

• Not really any magic, when you do the conversion of the repeating decimal 0.00010203...9596979900010203...95969799 ... you get 1020304...95969799 / 9999999...9999999 which just so happens to have so many common factors in the numerator and denominator that it simplifies to 1/998001.

• The nerd in me got giddy reading this...Love little math tidbits like this.

If I did this 10 years ago when I was bored in class, it's not news...

1/243 also gives a nice pattern.  (Credit goes to Richard Feynman)

• Mikko Rahikka

nope, 998 is missing, the same thing with 98 in the other decimal expansion

some people just see the pattern and assume it is followedfor every other number without any sort of proof bc he was playing some 5*8pixel resolution game instead of paying attention in math.

Hey, any number can exist. You just need a big enough canvas and good knowledge/talent with numbers. oh and btw  0 ÷ 0 = 0

• I've just had a nerdgasam! (That's my excuse, and I'm sticking to it.)

• T-1000s. nice.

• Douglas Stuart

Yeah. They're up to.... TI 83 and 84s now. Seriously, that's what all my students have. The 85 and 86 were so much better for actual science.

the 7's pattern is very interesting
