Mechanic: How many km’s have you done?
Me: 21 😊

Ps. I did the binary conversion in my head, that’s how deep I am in the matrix.

I still have to do 10000 = 2^4 = 16, and then 16 + 4 + 1 = 21 :( Am I bad?

@Japorized that’s how I do it too lol

Oh noes! I typed 10000 = 2^4 instead of 10000 ≡ 2^4! I’m gonna somehow remember that for a long time now.

@brod Oh nice! I’ve never checked my way of converting (thought of it once and just kept using it) so I never knew how others convert.

@Japorized I didn't even know ≡ was a thing 🙃

An engineering prof showed me how that method and I never really questioned it but for bigger numbers I fall back to a javascript repl

> parseInt("10101", 2)
> 21

@brod ≡ means equivalent but I’m probably abusing that notation 😂

I think it’s only relatively easy to count to some power < 10 unless if you’re really good with 2 digit multiplications. Like 2^5 * 2^5 = 32 * 32 = 1024 is probably hard to come by heart unless if you’re really used to it, or had mental arithmetic lessons 😂

binary that small I still do with the fingers (mentally of course), so 16+0+4+0+1

@nbamaral Same here but I start from the right.

@Divisionbyzero little-endian, eh?

@Japorized is this how unexpected factorial works?

See /r/unexpectedfactorial

@wildebeest Damn! xD That’s a good one. I never thought of it that way and have always been able to successfully tell the difference in my head based on context.
