What's the answer to this equation?

Please mods, leave this unmerged for a couple of hours, would be nice.

So there is this one equation that has been posted on many big internet forums and exactly 50% say that it's a certain answer, the other 50% says it's another answer (over 2000 people polled).

The equation is :

482(9+3)

So what's the answer to this problem?

The answer is 2.

Wait, it's 288.

That is pretty deceptive, but it is 288. Simple order of operation; brackets first (9+3)=12, then multiplication/division from left to right 48/2*12=24*12=288.

It's sloppy notation is what it is.

Going strictly by how it's written there, it's 288.

Actually I don't think it's a valid equation. What's 48/2*12? Is it 48/(2*12) or (48/2)*12?

Well the problem here is that 2. If it was 48/2*(9+3) its 288 because of the order you have to do it in. But if you have to do 2(9+3) first, then the answer is 2.

I'm an engineering student and I would say 288. It's just your basic BEDMAS. 482x12 going from left to right.

It's 288.

The correct expression would be :

48 : 2 * (9+3)

Which you can also write :

48 * (9+3) : 2

Or :

(9+3) : 2 * 48

Or... You see the point.

You don't have the brackets [ ] around 2 * (9+3), which means the multiplication sign is on the same level as the division sign.

The confusion comes from the missing multiplication symbol. It's common to avoid writing it though.

You're wrong.

Try typing it into a scientific calculator. The calculator is programmed to answer the equation in the proper order.

The answer is 2.

242(9+3)

Work to get rid of brackets first...making it

2412

Making the answer

2

Try it on your own calculator.

The way it's written, it would be 48/2 and then *12. Order of operations; since there are no brackets, you have to go left to right for the multiplication/division. Technically. it's neither 48/(2*12) or (48/2)*12 because simply adding brackets changes the level of priority of each calculation.

First I got 2. Then I did the equation and got 288. The answer is 288.

Using basic BEDMAS from highschool, I would say the answer to this would be 288.

That's probably the reason why you'll never see this equation written like this in any serious scientific book. It's just sloppy notation like Frogurt said.

48 2 X 12
24 X 12
= 288

the 2 and 12 are not in brackets together.

BEDMAS
brackets, exponents, division, multiplication, addition, subtracition

That's only if the lack of multiplication sign implies that there are brackets like this: 48(2(9+3))

482 x (9+3) What now?

you typed in 242(9+3)...you would get 2. I tried it on 5 calculators.

The reason you're getting 288 is because you're not solving the brackets properly.

You solve a bracket my multiplying what's in it right away with the number beside it.

Example:

2(4) would switch to 8...not 2*4. In the first step, you're supposed to eliminate that 4 by multiplying it.

Therefore 2(9+3) doesn't switch to 2*12...but to 24.

In this equation,the 2 is connected to the 3 and 9 right off the bat, but not the 24 at the start.
