40+40x0+1 ?

[minimuffy]

40 + 40 x 0 + 1 =

A- 1
B- 41
c- 0

I say its B-41 as you need to multiply then add. (from what i remember of standard grade maths the acroymym BOMDAS- brackets off, multiply, divide, add, subtract)

DH says its 1.

please tell he's wrong!

What did the zero say to the 8?

'Nice belt'.

That set theory book is ninety pounds

Why didn't Euler invent group theory?

Because he wasn't Abel.

I don't understand that joke schnitzel I think that knock at the door may be my old tutor with a big stick come to repossess my degree.

Dilys unless you did that sort of thing at postgrad level, you can consider yourself excused.

Other mners who are interested: I recommend to you this podcast by Marcus de Sautoy on a brief history of mathematics. Marcus de Sautoy is a bit like the Brian Cox of mathematicians but balder. He's very good though, and this series is very enjoyable.

noblegiraffe It's ninety pounds but so is a one night stay in a nice hotel. I know which I'd choose, which is why I always use my library :o Or Blackwells/Heffers second hand sections...

Dilys, but you'd better have got my joke!

There are 3 types of mathematicians: Those that can do mental arithmetic and those that can't.

Oh good, back down to my level.

(that was my joke. Hmphh)

Yes, I did get that one, and even the group theory ones, but schnitzel's little number clearly marks the point at which I run out of brain/knowledge, and I have to do a Captain Oates and let the rest of you go on without me.

If it's any consolation dilys I sat through 23 lectures on this sort of thing (punchline was line bundle) and felt fairly lost after the first 5 minutes of the first lecture. It was one of those courses where only the super-bright german guy in the second row had a clue what was going on, and everyone left the lectures groaning and clutching their heads.

I get that one jjkm. Schnitzel, your's are waaay above me as were the others of similar ilk.

I think I shall be putting that book on my Amazon wish list, knowing that my bro tends to buy for me from that, and maybe mention it to him too. I would rather have a book than a night in a nice hotel, but still can't afford £90 for either!

Anyway, I'm only on the level of Singh's Fermat's Last Theorem, which I enjoyed very much, and Alex's Adventures in Numberland. Suspect your recommendation would be flying further above my head than the clouds, but I'm learning and working really hard at my studies! I'll get there, I will.

Dilys - I lost the plot when alephs entered the scene. But then I'm under no illusions that I know much real mathematics - the original question is just arithmetic.

I'm only at second year undergrad level which is looking like primary school maths in comparison.

Hey ho, on we go.

changebags it depends where you are, as to when you do set theory at this level. And if you're a pure mathematician or a weirdo applied one Some places let second years do it, some third years and some at fourth year or postgrad level. If you've done a bit of abstract algebra in your first year, you've probably got what you need to read Enderton's book.

schnitzel, DP is in pain about the lime bundle. He may need therapy for the flashbacks...

Was the savannah joke about lion hunting, jjkm?

Interesting thread!

I got a bit lost at the 5+5+ etc. calculation because I did exactly what Lougle expounded in her 12 step theory and got -5. Which was wrong. And annoying.

I did lots of maths up to A level (double A level) and know about sq root of -1, imaginary numbers etc. but still got that wrong because I was being too rigid on BIDMAS (yes I learnt it some 30+ years ago, it's not new!)

and I got all the jokes except the lime bundle one.

Would second Alex's Adventures in Numberland. Strikes a rare balance between entertaining people who are new to real maths and telling people who do know a bit stuff they don't know.

I googled 'lime bundle' and found this which has links which explain (though TBH I cannot claim I fully understand the explanations but kind of get the jist) the maths fruit jokes mentioned, and add a fourth :

What is yellow, linear, normed, and complete?
A Bananach space.

My goodness, what wags they are
