Ok. New-ish to Ubuntu (MATE) at 16.04. I'm muddling through setting things up.

The difficulty in making a copy of a game disk depends on how new it is. Since it is a DVD I'm guessing < 6 yrs old. Some publishers use anti-cracking 'tricks' such as purposefully creating a...

I have never used WINE, but I think there's an option to enable CD/DVD communication in WINE which you may not be checking OR the CD is scratched quite badly.

*What I can tell you is the recent...

Thanks to all for the response. Perhaps I'll look into C++ so I can try both Qt and GTK+

In general, how does one "code/program" a GUI using GTK or Qt? Do I need to install some third party...

How do I get started using GTK+ and/or Qt (which I hear is going into future Ubuntu releases?) with C, because I'm decently comfortable with C? I can run these graphical C programs (using GTK or Qt)...

Hello all,

I'm interested in learning Java to create some GUI-based programs. I like the thought of Java being cross-platform AND graphical. I have learned the basics of C, but want to create...

Bought mine this morning! I'm really interested in Trine. I tested it this morning on Windows 7. Launches fine, although my laptop can't handle maxed out graphics. Looks to be well worth it for...

My explanations are based on my education, not a Wikipedia page. I have never seen or heard of any reason to evaluate an expression from right-to-left. If you want to apply mathematics to solving...

Because this expression is a single term, order of operations is used to solve it.

Because, based on the order of operations:
48÷2(9+3)
48÷2*(9+3) <- this is the only symbol (*) that can be...

You are right. It seems some people are either forgetting about order of operations OR were somehow taught to include 'implicit multiplication' as higher than regular multiplication. :confused:

48/2x is correctly translated as:

48 / 2 * x

People who translate it as:

48 / (2*x)

Are assuming, with no reason, that the 2 and x MUST be multiplied together. Because there's no...

This is the EXACT comic I've been thinking of :lolflag:

Basic algebra says:

48/2x = (48/2)*x Nothing in that expression means that "2" and "x" are multiplied BEFORE the division.

What WOULD be different is:
48/(2x) In this case the 2*x is...

Order of operations doesn't not allow for an elevated priority on implied multiplication.

I believe this guy is saying what I believe with better clarity. I wouldn't know HOW to incorporate that rule into the order of operations I learned: PEMDAS

I just can't understand HOW you can add in additional orders of operations :confused: It seems to me that, if another country teaches a mathematical method allowing these implied operators and their...

They are the same

x=48÷2(9+3)
x=48÷2*(9+3)
x=48÷2*(12)
x=48÷2*12
x=24*12
x=288

x=48÷a(9+3)

I would do:
48÷2
48÷(1*2)

same thing to me

People are INFERRING that those symbols mean more than than they really do. If you approach the expression based on order of operations:

48÷2(9+3)=?
48÷2(12)=?
48÷2*12=?
24*12
288

Anything...

which is the same as:
48/2*1*12
24*1*12
24*12
288

It is shocking how many people immediately resort to a calculator. Calculators are only as smart as their operators. It's more shocking that different calculators give different answers... :confused:

Incorrect Sir. The parentheses HAVE been dealt with as ONLY the stuff INSIDE parenthesis has priority. Once you have (12), you have 12:

48÷2(9+3)
48÷2*(12)
48÷2*12
24*12
288

Every time

Concerning:
Please Excuse My Dear Aunt Sally (PEMDAS)

Most people remember this mnemonic, but the disadvantage of the acronym is it cannot convey the fact that M & D carry the SAME priority...

I think that's what's confusing alot of people. I hardly ever see the ÷ symbol. I use / pretty much exclusively
