## How Much is Two and Two?

A mathematician is someone who pauses when asked “How much is two and two?”

Indeed, the answer might be:

**0**— modulo 4.**1**— in characteristic 3.**2**— if AND is considered as a logical operation.**4 ± ε**— for approximate values of 2.**4**— (almost forgot this case).**10**— in base 4.**11**— in base 3.**22**— for string concatenations.**MSC**— (this one is your homework).

replace letters by numbers, i.e. A=0, B=1, …, O=14, T=19, W=22, and then add modulo 26

+T W O

—————–

19 22 14 mod 26

+19 22 14 mod 26

—————–

12 18 2 = MSC

## Mr. Briggs:

You forgot 100, although I suppose that there’s no “2” in base 2.

“How much is two and two?” How much what?

I’m confused.
