48÷2(9+3) = ????

[Djmarkxr7]

Welcome to the light.

Yeah.

I can admit when I'm wrong.

I realized that I actually misinterpreted the equation.

48 divided by 2 is actually the FIRST equation in the problem, even though you do resolve 9+3 first which gives you 12 times 24 = 288.

I'm ok now.

 

[Van Allen]

288 easy

 

[LIH]

OK lets try this another way.

48 ÷ 2 x (9+3)

Parenthesis first

48 ÷ 2 x 12

Look at that. How could anyone think the answer is 2 lol
Seriously. We do equations backwards now?

 

[wiZe]

This is not debatable. Software often can't be programmed to understand all human conventions. Google, scientific calculators, etc. rewrite the problem as (48÷2)*(9+3) to indicate how they interpret the problem. Not necessarily to say it is the only correct answer.

Math is not perfect as long as it was created by humans. This much I understood after receiving my Masters in Applied Mathematics. Just because our science and math is damn good doesn't mean it's perfect.

It also boils down to communication. If this were written as:

48
2(9+3)

Most mathematicians would interpret the 2 as a coefficient to the quantity (9+3). Some conventions give higher precedence to coefficients than regular multiplication. Thus, the answer would be 2.

However, since computers can't interpret what you meant or what school of thought you fall into, it must rewrite the problem based on rules that it understands, such as pemdas, and go from there.

Thus, Google is correct. The answer to 48÷2(9+3), without knowing the author's intent, is 288.

However, anyone writing technical documents would be wise to write the problem more clearly.

 

[LIH]

Simple question:

Is this:

48
--
2x

same as

48
----
2(x)

or

48
-- x
2

Just asking?

Those are all the same. The answer is 24x. You do the equation from left to right plain and simple

Good analysis

 

[MadWun]

See no they are not all the same.

One will be 24x while the other is

24
---
x

 

[tre2k4]

Is there a difference?

I dont know if mean

48
---- = 48/2x
2x

or

48
--- x = 48/2 * (x)
2

This is the original ----> 48÷2(9+3)

Ok, let's remove the brackets, that should be the first computation.

Now we have 48÷2(12) = 48÷24 which is 2.

Remember 2 is multiply by what is in the bracket.

But you have to do division FIRST. Since its on the left. I will agree with you if you can prove that im wrong.

If it wasnt for the 48 you could just do distributive property
2(9) + 2(3) and still get 24


But since theres a 48 and a division sign, you do this step after you have finish anything that is [PEMA].
Then you multiply

 

[Rudey]

Honestly I really don't know where you guys get your math logic from.

I will go and say it is evident that there is not a lot of math major here.

Let's check the logics again. If you write it like this (48÷2)(9+3) the answer would be 288.

If it is written like this 48÷2(9+3) how is is that you ignore what's in the bracket and divide first. That just don't make sense to me. You always remove the brackets first

 

[PoppaSo]

this is the exact reason why the answer is 288

if there was no order you would be right.

48÷2(9+3)

This has precedence because of brackets to the right of equation.

48 ÷ (2(9+3)
Once you start precedence I don't believe you can just drop it and jump across one operator (x) to do another (÷) which you say are the same. You switch order for no reason when after establishing precedence.

(48÷2)(9+3)

when you do this you are putting division over multiplication thus breaking your own rule if they are the same...you skip the multiply to divide, so you jump over to order to divide .

48÷2x12=

12x2÷48=

that's not the problem.

the problem is.

48÷2(9+3)

parenthesis first.

48÷2(12)

parenthesis are still there.

48÷24

Ok, now they are gone.

2

 

[letsshoot]

i too thought it was 2 but that was until i was getting different outputs.
i even busted out my ti-83 and it's output was 288.

yep your right come on players the answer like nubian says is 288

 

[tre2k4]

Those are all the same. The answer is 24x. You do the equation from left to right plain and simple

wrong

48
---- is the same as
2x

48
---
2
times
1
---
x

not

48
---x
2

After you do whats in the bracket, the bracket becomes a multiplication sign

48÷2(9+3)
=
48÷2*12

You can find that in any math book

[stizz3000]

cant believe this thread is this long..

 

[godofwine]

Please excuse my dear aunt sally (parentheses, exponent, multiplication, division, addition, and subtraction

So the answer is 2. I was a mathlete in high school

You have to be a complete retard to believe that today's software can't handle a simple ass pemdas rule

Hell, I could write a MATLAB script in minutes to give the INCORRECT answer that y'all want it to be. Excel has been out for nearly 2 decades, if such a gaping (simple fix) incorrect procedure existed it would've been corrected by its second release.

The ignorance on some of you

I assume you failed reading throughout your schooling. That's not what I said.

I know how to write in Matlab, C#, SQL, and other languages too. So what's your point?

 

[LIH]

See no they are not all the same.

One will be 24x while the other is

24
---
x

Yea you're right. In the case of 48 over 2x would make the answer to the original prob 2. So my analogy was bad. The 2 and the x should be seperate terms

 

[tre2k4]

Please excuse my dear aunt sally (parentheses, exponent, multiplication, division, addition, and subtraction

So the answer is 2. I was a mathlete in high school

So you multiplied before you divided even though the division comes first

After you do whats in the bracket, the bracket becomes a multiplication sign

48÷2(9+3)
=
48÷2*12

You can find that in any math book

I see your point but again it is not logical.

According to your logics then 48÷2(9+3) = 48÷18+6

What you are doing is changing the purpose of the 2.
Keep in mind that whatever is in the bracket is double first (which is multiplying by 2).

Hes right tho, sorta.
Computers can be dumb, meaning you have to specifically type out what you want to solve. Like in some calculators need you specifically add parentheses around everything or otherwise you will get the wrong answer. You have to type it in a way that makes sense to them.

I'd give that medal back homie.




Just fucking with ya...............you are wrong though.

 

[PoppaSo]

Dammit, I'm waffling!!!

It's been a long time since I've done problems like these but I'm going to flip flop and switch to 288...Fuck!!!

48/2(9+3)

48/2*12

Since division and multiplication are the same...

48/2 = 24*12 = 288.

FUCK!!!

48/2 = 24*12 = 288.

Where did you get the (=) sign in this 48/2*12 ???

You completely redistributed the problem into an equation without any math.

 

[LIH]

Still 288 tho. If 2(9+3) was meant to be a single term it would be in parentheses.

 

[tre2k4]

I see your point but again it is not logical.

According to your logics then 48÷2(9+3) = 48÷18+6

What you are doing is changing the purpose of the 2.
Keep in mind that whatever is in the bracket is double first (which is multiplying by 2).

No my logic is because theres a 48÷ before the 2(9+3)

you CANT use distributive property. You solve whats in the () first and then the () turns into * because theres a number in front of it. 2(9+3) = 2*12

You can leave the () there if you want: 2*(12) but its all the same thing

2(12)=2*12=2*(12)

Fam, Rawness obviously didn't read all that I wrote or reading comprehension is a challenge for him. This porn induced ADD is a mutha!

 

[tre2k4]

48÷[2(9+3)]=2

48÷2(9+3)=288

The point is, the underlined below is complete BS:

However, anyone writing technical documents would be wise to write the problem more clearly.

First, there is one and only ONE answer to the equation. There is no ambiguity.

Second mathematicians know the answer is 288 not 2, and if you were right and it was 2 it would be an easy fix (if you really write in those languages then you know that....that was the point of my MATLAB script statement, duhhhhhh)

 

[wiZe]

Thanks. You confirmed that reading comprehension is a problem for you. Please do tell us which university you attended. I will submit a formal complaint.

[maxwell27]

I think you mean left to right and I think you are correct on multiplication and division are the same. Fuck I failed.

I concur with you and him. 288

You have to specifically write out what you want to solve wether inputting it into a computer or leaving it for a mathematician to solve. There is no ambiguity here.

Calculators are different because some have limited computing power, but a TI-83 and more powerful computer software are going to use established conventions like pemdas. No ifs ands buts about it.
