Even I don't live in US, no.2 got me, duh.

I satisfy all (especially 5 >.> and 6 :P) except #1 but that's work in progress :D

I don't get number 9.... can someone enlighten me?

i think it means that whenever you write "for all", you follow it by "there exists", so for every "for all" there is a "there exists".

Yes. :)

Hmm, guess I'm not a mathematician -- I'm European and I'm currently studying for a Bachelor's degree in Computer Science. However, the other 7.99999... are spot on.

You really aren't a mathematician if you are studying for a bachelor's degree in CS...

What if I'm studying for two bachelor's degrees in CS as well as a bachelor's degree in applied mathematics?

How can you explain all of the wonderful mathematicians that have contributed over the centuries with NO formal training or degree? Srinivasa Ramanujan, Sophie Germaine, Gauss was solving mathematical quandries before he was in his 20s. Are they not mathematicians?

You fail at #7.

For #9: this should allow you to purchase, with exact change, anything from $0 to $.99. (OK, you can purchase a bit more as well....)

"I'm not a mathematician"
He said it himself

For each "for each" (inverse 'A') sign there is at least one "there is at least one" (inverse 'E') sign.

Am I the only one who noticed the missing apostrophe in #4? Wait, does that make me an English major? Noooooooooooooooooooooooooooooooooooooooooooooooooooooo!

Hmmmm for #3 I have to say that Latex has a few "proper" pronunciations. The 'a' can be a long a as in 'base' or a rounded one as in 'father'.

Re #4: Ordinary or is neither xor nor mathematical or. (If you're a mathematician, you can parse that.) Consider "coffee, tea, or milk?"; xor would permit all three, but that's not what's meant.

What if I want Coffee and tea with milk in it?

#11 - Making corrections to a math comic.

And how you know you're a philosopher: when I showed this to my husband, he said "there's a use/mention distinction missing from #9..."

I don't understand #5. Why would it take a mathematician that long to figure out a check?

Because they get wrong answers the first several times they calculate it.

And re 7: I critiqued the texts in at least two logic classes because they did not make use of iff statements, only deriving if-then statements and using them. But, iff, as mathematicians know, is much more powerful: you can substitute one side for the other wherever it appears in a statement without affecting the truth value.

Perhaps it's about trying to decide what to do about the 1/750th cent? I don't get it either.

Mathematicians are usually EXTREMELY bad at calculating stuff. (Boring & applied.)

Arithmetic is for calculators.

I read these in David Letterman's voice. Totally laughed at #7

crap meant to say #8

I'm a Maths and Computer Science AND English major ^_^ Most of these hold, especially 5 - my Fine Art student friend calculates change quicker than I do.

(For those who don't get it - the higher you go in Maths the less numbers you deal with.)

On that note, you missed a point: you know the Greek alphabet.
And now I pass #11 as well :)

#0 you don't really mind that there is a #0 or the fact that you have exceeded the 9.(9) (twice already, counting #11)

#-1 you could come up with at least one more statement that defines Mathematics just that you get "morally" back into the 9.(9) range

Guess I get it, but it's not the greatest example, because you're assuming they'd care that much about the exact result. Any normal people would round up and each pay $33. Or are you saying Mathematicians aren't normal!? :-o

#11. You understand this comic

Well, of course, it takes 20 minutes to split $84.76, because we only have 3 quarters, 2 dines, 1 mickel and 4 pennies in our pockets, given a mathematician's paycheck. It takes a while to scrounge up the money from other sources.

Shouldn't that be a NAND instead of a XOR?

umm, if you ask for Coffee AND tea, wouldn't you get nothing (Everything that is both coffee and tea)? I like to use this as a example when people tell me that double negatives are wrong because they don't follow Boolean logic. And if the waiter said coffee XOR tea, wouldn't that be asking if you only wanted one of them, but not which one?

Another example... a man claims that a girl led him on by saying "No, no... a thousand times NO!". Well, that's 1002 NOs, which of course pair up to 501 YESs, or YES!

Ordering Coffee Xor Tea is only confusing if you respond, "Yes."

All for one, one for all? #9

#12. You not only have your own geeky math webcomic you write geeky math guest comics for other geeky webcomics.

Actually - 3 quarters, 1 dime, 2 nickels and 4 pennies....

I struggled with 9 because I was reading it as A(AE)E, rather than A(A)E(E).

Hm... I guess I don't quite qualify as a mathematician. Some of those are really funny if you stop to think about them :)


I cover all, but the number 1, however I'm a chemical engineer... always wanted to become a mathematician :(

Ha, I fit in to half of these. Well on my way :)

I'm a physicist and eight of these apply to me. But I have a real hard time understanding #4. Is it just some strange wording or do I not understand Boolean logic? I mean, the waiter really does mean OR - you can order a tea, a coffee or both - it's not forbidden. Can someone help me out?

I dunno. How many times have you seen a person order both coffee and tea at the same time? Plus, it's more expense for the restaurant (if they only expect one to come with your meal). A more appropriate example, in the case of a breakfast meal, is ordering one egg scrambled AND sunny-side up.

I don't see how that's more expense for the restaurant. The same waiter will bring you both coffee and tea. It's more profit, because the restaurant sells two things at the same time. And apart from being a bit unusual it's still not forbidden. I mean the waiter might be surprised, but it's not like he's gonna say: "You can't order both coffee and tea because I said 'coffee OR tea'".

I got:
6 (kinda)
5 (probably)
3 (half, I'm not 100% on LaTeX)

I'm a masters student in Mathematics, but no.10 bugs me! Always has.

#12: You play monopoly with dice whose faces bear (1,2,2,3,3,4) and (1,3,4,5,6,8) dots respectively, rather than the usual ones.

Number 2 is the minimum amount of coins needed to always be able to give change in coins.

Number 2 is the minimum amount of coins needed to always be able to give change in coins.

I just posted my own version for CS. Thanks for inspiration ;-)

Re: James
Ah, but with those dice, you've decreased the odds of doubles from 1/6 to 1/9, thus changing the odds of taking an additional turn (and of going to jail after rolling doubles three times).
