MIT cheer: I’m a Beaver, you’re a Beaver, we are Beavers all. And when we get together, we do the Beaver call. E to the U du dx, E to the X dx. Cosine, secant, tangent, sine, 3.14159. Integral radical mu dv Slipstick, sliderule, MIT. Go Tech!

I’m not 100% sure you are joking, so just in case:You can actually prove mathematically that π is irrational. (Furthermore, it is transcendental.) Irrational numbers cannot be represented by a finite number of decimal digits unless you are rounding.

I still have one that I bought with paper route profits in 1970, and can still use it (well, most of the scales, anyway). Also have an old HP-65 that unfortunately has a few LED segments out.

Pi backwards? That IS a challenge (I can only go to 3.14 when going forwards.)

## Richard Howland-Bolton Premium Member almost 7 years ago

They’d have to specify how many decimal places to start from. I’d say 5,000 would be a good place.

## toto23 almost 7 years ago

π being irrational, its decimal representation never ends, so you can’t actually recite it “backwards”.

pi backwards:(1 + i * 2) / i ^( -1) of infinity to 0 = i from summation the * 4

E-I-P. Dang. I lose.

As far as we’ve been able to calculate so far …I’m not 100% sure you are joking, so just in case:You can actually

To even speak of the “last digit” of Pi is nonsensical, so the contest makes no sense.

## neverenoughgold almost 7 years ago

I think they are confusing “Pi” with “pee” here. After all, he who “goes first” loses…

## josh_bisbee almost 7 years ago

Pi has over a billion numbers after the decimal without a pattern

At least they’re staying out of trouble…for now.

I like the MIT cheer.

Pi is exactly 3!!!!

Sorry I had to do that but now that I have your attention i’d like to talk to you about Life Insurance…

Since he said a number he’s out
