The Math Game

[Glaurung]

(3^4 - 2) * 3 * 5  (or Byzantines 1, Normans 0, at full time)

1261

[Glaurung]

(2^2 * 3^2 *5 * 7) + 1

I thought I'd try to revive this, since I seem to have killed it.

For a subtly festive theme: 359

[Glaurung]

15^2 + 6 or 2^8 - 5^2

91

(13*14)/2 = 91

[Glaurung]

((2*5)^2 + 3) * 5 = 2^11 - (3*11)

2768. It's closely related to the previous question; extra points if you can say how.

Extra points: it is also maths as is the other question. Points plzzzzzzzz.

[Glaurung]

314,159,265 / 100,000,000 (it's not quite pi!)

[Othko97]

2.

[Glaurung]

1 / (1/3 + 1/9 + 1/27 + 1/81 + 1/243 + 1/729 + ...)

This is perfect for tomorrow's astronomical event: 28

[Othko97]

7*2*2

ln(2)

[Glaurung]

ln(2) = 1 - 1/2 + 1/3 - 1/4 + 1/5 - 1/6 + ... + (-1)ⁿ⁺¹/n + ...
This one was interesting   It took a bit of research 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:

1683

[Jubal]

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

I'm sure you were going for something else though

[Othko97]

Need another number Jubal
