Stuff like this makes me a little crazy! I know, I know.... short trip, right?? WOW!!

 

[Cougar]

Yeah, that's pretty crazy. I always thought the repeating fraction 1/7 was pretty weird

1/7=.142857
2/7=.285714
3/7=.428571
4/7=.571428
5/7=.714285
6/7=.857142

Looks like a pyramid scheme to me, Tom.

I'm no math whiz, but someone showed me that in junior high school and I used to show it to people by doing it out one step at a time. Clearly more impressive before computers and the Internet...

3/7=.428571
4/7=.571428
5/7=.714285

A fraction to decimal conversion pattern?
Thanks Coug for triggering a 360 degree brain rotation!

1+1=

That is pretty much where I lost interest in math. I only went to school for lunch.

1-1 was a racehorse
1-2 was one too
1-1 won one race
1-2 won one too

 

[chazmo]

That is very cool.

Once upon a mattress I used to be into number theory. I don't remember seeing this little sequence before. I'll bet this translate into other "bases" as well. Haven't tried it though. Might start playing with it a little...

 

[davismanLV]

It's fascinating to be sure.... it kinda makes me wonder. About what, I'm not sure.....

Looks like Abbot and Costello's math routine.

I'm not really a number guy (unless you count using the Nashville Number System for simple charts), but you might like this:

A performance of "Mathemagic"

In a lively show, mathemagician Arthur Benjamin races a team of calculators to figure out 3-digit squares, solves another massive mental equation and guesses a few birthdays. How does he do it? He’ll tell you.

I have 2 of Prof Benjamin's Great Courses courses.

Some numbers are handy in life, the time, prices, speed limits, etc.

Then they start turning into a bummer, your age, your height, how much time you have left, etc.

I do a math exercise in my head where I start counting, and while counting I start doing other calculations, like multiplications.

I'm left handed so extremely right brained, doesn't make math my primary mover, I'm more guided by feelings.

Oh wait! Wrong thread!

Random song review - whenever this song came on the radio, I changed the station as fast as possible.

[davismanLV]

Me too!! What a dreadful song....

 

[Guildedagain]

This is the real deal here, cry a little ;]

Some of you should have points taken away for posting crap like this......

It looked pretty wild and cool. It took a minute to find the pattern and then it made sense. I suspect someone did a couple in homework and the pattern jumped out at them, and the finished the sequence. I was never great at math all the way through school. I was good enough to be able to move to the next class in math though. All the way through college too. I found that how it's taught makes a big difference.

 

[beecee]

Cool...I like math..work w. numbers every day.

Been doing a lot of multiplication on paper vs calculator recently as I had noticed I couldnt do multi figure calcs in my head, much better now.

I get odd looks in meetings from the "kids" while doing quick NPV's by hand on a particular property we're discussing.
