48÷2(9+3) = ?

... Go back to simple math.

Heh, I actually have a theory on the cause of all this commotion: Us being acquainted to more complex mathematics, mainly algebra, we tend to forget the simplicity of simple problems such as this. We are very used with the x and y equations that we try to apply it to this one too (not that it shouldn't; I'm talking very down to earth here).

For example, take the equation x²/y(x+1). Upon seing the equation, we would do the groupings first and then distribute it, as we know we can barely do anything with dissimilar variables. Since almost every problem bombarded to us usually involves dissimilar variables, it becomes instict to simplify everything first and mostly do division last.

My teacher always told me: "Once you become an expert engineer knowing complex things, you would tend to forget even the simplest of equations"

Very well put arkhi.

The way I was taught, you do the (9+3) first, multiply 2 with 12 and only then divide 48÷24.
It may be years ago, but I can still remember the basics of mathematics.

Dennis, is it true Wolves pee in the woods?

Yes, but if no one is there to hear it...

Someone actually knows how to do an Algebra formula besides me.

This thread holds the record, most pages in the chillout room, before going off topic

 

[Hopalong X]

We can fix that.

 

[SIW2]

Correct answer is 2


Not many votes cast tho.

 

[alfred01]

Wow. Don't overthink it folks. Go back to simple math.

48÷2(9+3) Once you do the work in brakets this question becomes
48÷2x12 At this point you follow the math rule that you do complex problems in the order they appear, which gives you
24x12= 288

For the formula

what is the value of d when u = 3, v = 11 and t = 5?

Like I stated before where is the division sign? There isn't one.

The division sign is replaced by the slash making it a fraction and it is placed EXACTLY where the division sign was.

48/ 2(9+3)= 2

Well for 2 cents I could have told you that from the git go!:roflmao::roflmao:

The division sign is replaced by the slash making it a fraction and it is placed EXACTLY where the division sign was.

That's just different notation.

Division is often shown in algebra and science by placing the dividend over the divisor with a horizontal line, also called a vinculum or fraction bar, between them. For example, a divided by b is written



This can be read out loud as "a divided by b", "a by b" or "a over b". A way to express division all on one line is to write the dividend, or numerator then a slash, then the divisor, or denominator like this:

48÷2(9+3) = ?

Two answers: 2 or 288

I first saw this on another forum and then subsequently on others. The amount of threads arguing which answer is the correct one is hilarious.

So where does SF stand?

I think I found the division sign Mike. Give Topper an apple for me will ya? Thanks

Only important if you want to find the right answer. :shock:
