I got these problems(questions) from various route.
I got this matrix problems from high school book(test book for exam).

f of x, f(x) is math.
Problems of questions, problems(questions) is not math and it's bad
English.  The proper punctuation is "problems (questions) from"

problems(questions) : bad english.
problems (questions) : good english.

Really ?
What's the difference between the two?
Maybe, space bar~

Yes, the space bar. A space is to precede '(' and follow ')'
A space is also to follow these punctuation marks
, . ; : ? !

Indeed, it's even preferable for two spaces to follow
. ; : ? !

When math is typesetting space is put before and after
= < > <= >=

It makes for clear and easy to read text.

to mina_world:

Unless you want to end up talking like William Elliot, ignore his
"English" lessons.

Instead:

(1) Choose carefully selected books written in English -- certain math
books may be fine.

(2) Read newspapers -- for example, The New York Times., and make
notes (index cards are good) of words, phrases, idioms, etc.

(3) Watch movies in English.

(4) Make audio tapes of native Koreans who speak English _very_ well,
from your point of view -- perhaps diplomats, or other public
speakers. Use these speakers as models. Get 2 tape recorders, one to
play the tape of your model, the other to record yourself saying the
same sentence as you hear from the model. Play them back, and compare.
Keep the old tapes of yourself for later comparison (and amusement).
Over a period of a few months, you should hear a substantial
improvement in your own recordings.

I'm just mediocre in Korea.
Of course, other people in korea do not use sci.math well except me.

You are asking on behalf of both yourself and others?

Some people hare are thinking that your are posting upon the behalf
of others besides yourself.

I never claimed it as a fact, nor did I even think it was probably
true -- it was just an idle speculation, nothing more.

I regret having even suggested it.

But let me point out, Mr. English teacher, that there are at least
three errors of English in your previous sentence ("hare, "your",
"upon the behalf").

We do not consider that wrong,

Who is _we_? Is there some kind of committee? You should have used
"I".

but it would be nice to know rather than surmise or make rumor.

Well, she has the right to privacy, as we all do, so I regret having
posted the idea, since now she's being cross-examined by the
inimitable William Elliot.

Will you clarify for us if you're a lone poster like most of us here
or if you are posting upon the behalf of others in addition.

Leave it alone, William -- bad precedent.
