I have to do all that to become a mathematician! It's easier to think that i am a mathematician.

There are 10 kinds of people in the world,people who understand binary and people who don't.

Okay, but how many of them apply to you

I am afraid none of them. I am feeling very dejected. Can you make another list?

Thanks for providing the new list. I have one of those.

Those are two logic symbols. For all and there exists. But I do not get it.

The other one is incomprehensible to me. I only got 3.

How much do you score on the first list?

How do you pronounce LaTeX?

I scored zero and am glad of it.

lah teck I am pretty sure.

How can you score zero? Don't the following apply to you?

It is understood I am only buying one. Who buys two cars.

I would never use any math on any woman. Not unless I despised her.

DE's are nothing more than approximations. Then to solve them one usually has to resort to numerics or linearize them further turning it into an approximation of an approximation.

Does that stop you from using the XOR operator?

Really? Would you use math on chocolate chips?

approximations.

You surely use them a lot

I love XOR. My favorite command back in the old Z-80 days was XOR A.

Nope, I eat chocolate chip

They do crop up in numerical analysis. But as you know I never do any physics.

Showing that the author of that page probably never even seen a Z - 80!

#3 of your second list is the one!

Hi Agnishom

For #9: Do you know what those symbols mean by themselves.

For #3: I thought LaTeX was pronounced lay teck.

In mathematical logic the two symbols are used to express certain facts. For example:

Meaning:

For every x there is (at least one) y which is greater than x,

Or, even further simplified:

There is no largest number.

The thing is, it is very common to have an exists symbol right after the for all symbol, like in the expression above. So, the joke would translate to:

For all for-all symbols there exists a there-exists symbol.
