I always knew it would end like this.

Now how do I extend the zeta function to s<0?

\zeta(-1)=\sum_{n=1}^\infty n^{1} = 1+2+3+...=1/12

\zeta(s) = 2^s \pi^{s-1} \sin \left(\dfrac{\pi s}2\right) \Gamma(1-s) \zeta(1-s)

I don't believe that counting is really that critical to problem solving. You have to know how to phrase a problem, and how to solve for a value manually, but developing a numeric solution is something that computers are much better at than humans. If you actually end up needing to add complex fractions by hand on a regular basis, you'll learn. I don't know how much value there is in teaching kids their times tables by rote these days. Learning algebra - how to manipulate variables - has value but even then it's just the language you use to describe things that are actually interesting.

Speaking of which, have you folks read Lockhart's Lament? I imagine most of you have but it's a great essay to read and think about if you like math, particularly how it's taught versus how it could be.

i like dis essay its good

Emergency confection port.

You know, they say all men are created equal, but you look at me and you look at Samoa Joe, and you can see that statement is not true! See, normally if you go one-on-one with another wrestler, you got a 50-50 chance of winnin'. But I'm a genetic freak, and I'm not normal, so you got a 25% at best at beatin' me! And then you add Kurt Angle to the mix? Your chances of winnin' drasticy go down. See the three-way, at Sacrifice, you got a 33 1/3 chance of winnin'. But I, I got a 66 2/3 chance of winning, cause Kurt Angle KNOWS he can't beat me, and he's not even gonna try! So, Samoa Joe, you take your 33 1/3 chance, minus my 25 percent chance, and you got an 8 1/3 chance of winnin' at Sacrifice! But then you take my 75 perchance chance at winnin', if we was to go one-on-one, and to add 66 2/3 ch... percents, I got a 141 2/3 chance of winnin' at Sacrifice! See, McJoe; the numbers don't lie, and they spell disaster for you at Sacrifice!
