How many poeple

[Trivium Nate]

I learned binary but ive forgotten it lolz

 

[DJ-CHRIS1]

I dont memorize it but I know it.

I taught myself how a year ago when I was in 8th grade, but it was an extremely vague understanding. It'd take me quite a few minutes to convert, say, 145 to binary. But now I understand it a little better, and am able to come up with 10010001 relatively fast (that is it, right?) Then base 8, base 16, etc. etc. came almost naturally to me; though I have a hard time, compared to base 10, multiplying them and stuff. We don't really have any good computer classes in my school . Gotta take one on Powerpoint and stuff next year, then I have the option to take a year of C++, that's about it. Honestly, I don't even know what CSS & CISCO are. (Unless you're talking about Counter Strike...lawlz0rz, jk)

But at first, I was like, "how does C*E=A8??? that makes no sense." That's how all my friends are now when I try to explain it to them. Almost like their faces when our teacher taught them the concept negative numbers. Can't wait to see how they react to i... I know that there's weirder stuff than that, it's just that's about the weirdest concept I know as of right now. (I'm a tad ahead of the others in my math classes...all started when my brother taught me multiplication in preschool... call me a nerd if it makes you happy)

C*E=A* makes perfect sense to me...

the question is does

Q = !(A+B) + C = A*B + C make any sense to you? (it's boolean algebra)

 

[THEpiGUY]

Afraid not... If only I knew what a "!" before parentheses was and what Q is... It might also help if I had ever heard of boolean algebra before.

But C*E=A8 makes sense now, it just didn't a year ago. I have a better understanding now.

I don't know much about boolean algebra, but I do know that when we were doing Scheme programming there was a data type called boolean that came from boolean algebra and it produced either "true" or "false". for example, this program uses boolean as an output....
programName: num -> boolean
(define (programName number)
(>= number 35))
(programName 35) -> true
(programName 10) -> false

EDIT: I'm not sure if boolean is used in other languages or not but scheme uses it. I don't know much about boolean algebra but I'm going to guess it uses something similar to that. Sorry to go off track here, I just thought I'd throw my 2 cents in.

I don't understand boolean... IN fact we had a test the output was either going be 1 or 0. I just guessed got a A on it

What happens if I take a Ipod nano and edit its HEx and put

How does Hex work..

 

[Natalya1]

i can do binary, hex and octal

 

[mark thorpe]

im just learning how to do those at college at the moment.. did the basics yesterday, more detail next week.. fun fun.. (electronics, not computer stuff)

i also have to learn basic programming this year.. C++ and all that.. not looking forward to that..
