I went ahead and started reading "Who's Afraid of C++?" as suggested.  =
Surprisingly, I also became more and more intrigued.  It was actually =
starting to help me better understand places where I was getting stuck =
in my other studies of C. =20

I'm utterly *terrible* at math, but as I continued to study all this =
comp. science, a light in some dark, unused part of my brain began to =
slowly brighten, and I was beginning to understand!  Eureka!!

...of course, that would be the point where I crash into some kind of =
math problem that completely trashed my new natural high.

And, here it is!

Using the hexadecimal system, answer this problem:

1a + 2e =3D

Welp, 'Susan' said she got 48 for an answer.  Well, I got 41.  Not only =
was I waaay off, but when I saw how the answer *should* be worked out, =
it knocked me into next week!  (meaning it blew me away)

...and, here's how it's worked out!

1(1 * 16) + a(10 * 1)=20

2(2 * 16) + e(14 * 1)=20

------------------=20

3(3 * 16) + 18(24 * 1 =3D 1 * 16 + 8 * 1)=20


"Carry the 1 from the low digit to the high digit of the answer, to =
produce:=20

4(4 * 16) + 8(8 * 1), or 48 hex, which is the answer"

Well, I could only figure just so many guesses as to what all this =
means.  But all in all, I honestly have no clue. =20

All I can figure is:

* In a multi-tasked math problem, division and multiplication are worked =
out before addition and subtraction.

* I'm guessing that the 4 parts to the problem represent the 4 places in =
a binary code that altogether make up a hexadecimal.  How "way off" am I =
still?  Probably very...


Would anyone who is gifted (to any lengths) in the realms of math and =
comp. science be willing to share in the gift and please help me out?  =
My math knowledge only goes as far as a small crumb of geometry.

Thanks a Million,

Me

Yes, the order is supposed to be
1.    Power
2.    Multiply
3.    Divide
4.    Add
5.    Substract

In Dutch we had this simple line: "Meneer Van Dalen wacht Op
Antwoord".
Where the caps stand voor de first letters of the words (in
Dutch of course) that present these 5 operations.

I am not exactly sure what the question is here. As it does not
quite dawn on me what the problem is in:
1A
2E+
