maths lesson, link and meme [of sorts]

the maths lesson
ok, this week at uni i learnt....

that   -128₁₀   to   +127₁₀          can be expressed as
         2^-7         to   2⁷-1

this is clearly bollocl<s.

the meme

"Ok, I was browsing the interest lists of LJ today and saw that the top spot on the interests was music. All well and good - but lets face it - dull as shite, right? So in my infinite wisdom I have decided to try to alter this sad state of affairs. To this end I need your help - thats right, yours! I have found a phrase that is not on anyones interest list, and I will, after this post, add it to mine. I expect everyone on my friends list to add it to theirs. I also expect you to ask your friends to do the same. As such a wave of this interest will sweep out and, hopefully, conquer livejournal! The goat is gonna get it! The phrase that you should add to your interests is:

isn't that just the principles behind binary?

i think it's meant to be... he was trying to explain using sign bits.

[king-of-spook.livejournal.com]

ah yeah, he's using the subscript to try and say if its decimal or binary, but its a bit of a shit way of explaining it!

[king-of-spook.livejournal.com]

oooh and i jsut noticed the big fuck up! 2^-7!

what an idiot

[crazymeandave.livejournal.com]

my thoughts exactly.
i pointed it out and he said i was wrong 'cos he'd copied it from a book

[king-of-spook.livejournal.com]

totally off topic, but, just wondering if've still got the pics from my party?

[crazymeandave.livejournal.com]

yeah. have put them on a cd for you, but can email them to you if you like.

[king-of-spook.livejournal.com]

sweet. we should meet up sometime and catch up.

[303factory.livejournal.com]

heh I dont even know that notation O_O

[crazymeandave.livejournal.com]

the subscript tens denote it's in denary.
the superscript sevens are indices or powers...

meaning that i was told that -128 is the same as 0.0078125... which is clearly bollocks

[bluekieran.livejournal.com]

That does indeed appear to be bollocks. Are we missing something?

[crazymeandave.livejournal.com]

nope... i'm just shocked that someone lecturing at a university can make such an erroneous statement about something in which they are supposedly an expert.

[muntafara.livejournal.com]

i haven't done maths for over 4 years now and i can see straight off that that is bollocks! what the fuk kind of university do you go to?!!! is the world full of imbeciles?!! *the-state-of-this-country's-education-system-fuelled-anger* rah!
