Focus and memory test

A while ago I was forced to listen to religious-babblers: so I started calculating 2^x to see how high I could get. It took a long time (10 hours), but I managed 2^37; without being an idiot[-savant] (I notice a lot of idiot-savants here).

So how high have you gotten? Especially if your CS, can you rattle off 2^32 without a calc or your phone?

(I'm curious because of all the cell-phone crack-heads I see in McD's checking their 3-digit order number, again and again. They're so ignorant--brain-damaged--they can't memorize 3 lousy digits. It's beyond pitiful how many autistic, ADHD kids--and adults--are out there: many of them attending college or university but unable to learn or to ever be useful, intelligent members of society.)

>A while ago I was forced to listen to religious-babblers

Martyr yourself, weakling.

What a waste of time. You could have been thinking of solutions to famous, new and/or useful mathematical problems

umm.. If you did that in base-10 then it is kind of impressive.

>2^37
I hope you mean 10^100101, son

2^2

>2^32
429_______

We're told 2^2 is 2 but it should be 1 otherwise of what use is 2?

really made me think

I like this approximation
2^x ~ (1 + 0.025*floor(x / 10)) * 2^mod(x % 10) * 10^(3*floor(x/10))
With this you can compute 2^x for high x in your head and impress people.

"Hey man do you know 2^9?"

why are you people like this


just use a fucking calculator

It's not that bad, maybe it's more clear what you should compute when written like this
2^(10x + y) ~ (1 + 0.025*x) * 2^y * 10^(3x)

you're

>implying that isn't the normal reaction to mess with a brainlet who doesn't know 2^9 is 512

>people who have hobbies outside of doing arithmetic quickly are stupid

this board has gone to shit

2^10 ~ 10^3
so 2^10 = 1024
2^9 = 2^10/2 = 512
it's not exactly hard. and I can't be arsed to go look for my calculator

> he doesn't know his powers of twos.
Each takes like 3 seconds to calculate if you've not already memorized them, certain ones come up a shitton, like 2^10.

only now up to 2^16

it's 10000000000000000000000000000000000000

Use the square-and-multiply algorithm to calculate larger powers.

someone fucking screen cap this pls
i can't breath

I have everything up to 2^16 memorized from working with 8 and 16-bit machines
