OK all you nerdy, geeky, math nerds like me. Here is the ultimate math game.

You make an equation that will equal the number the person before you enter. And below your answer provide a new number for the next person...

example:

It goes like this...

The Khan: 25

person #1: 5*5 next: 100

person#2: 50*2 next: 628

person#3: 60x10+2(14) next: 134

etc.


I'll start.


74

(2*2)+(((6*6)-1)*2)


831

830.99999 + 0.00001


5

e+((10/2)-e)

0

(((3x^2 - 27)/4) * ((8x^2)/(9 - 3x)) / ((x^2 + 3x)/6))*0

This one was interesting :)  It took a bit of research (http://mathworld.wolfram.com/NaturalLogarithmof2.html) to find it.

Alas, I'm not nearly as good a mathematician as Othko, and I'm struggling to come up with anything as subtle. So, from a completely different source of numbers:

(((2*2*2*2)*(2*5*5))-17)+(2*5*5)

I'm sure you were going for something else though :P

Hmm, I didn't realise this was a triangular year.

Also of note is that 2016 = 741+1275 = (1+2+3+4+5+6+7+8+9+10+11+12+13+14+15+16+17+18+19+20+21+22+23+24+25+26+27+28+29+30+31+32+33+34+35+36+37+38) + (1+2+3+5+6+7+8+9+10+11+12+13+14+15+16+17+18+19+20+21+22+23+24+25+26+27+28+29+30+31+32+33+34+35+36+37+38+39+40+41+42+43+44+45+46+47+48+49+50)

A googolplex

By definition, 10 to the power of a googol (where a googol is 10¹⁰⁰), so 10¹⁰¹⁰⁰. If we use the ^ character for powers, it's 10^(10^100). It's quite large.

Something a bit smaller: 2,187
Hint: there's a way to write this with only two characters.

EDIT. Bump. Is anyone still interested in this?

I had to mess around with a calculator for a while* to get this one: it's 3⁷.

Here's another one with a two character expression possible:

40320
