48÷2(9+3) = ???

[major pain]

Why would a 2 factor into the parenthesis alone, when it's 48/2 and not just 2? 48/2 would factor in.

As the problem is written it "should" be assumed that the (9+3) is in the denominator. Anytime I've seen a problem like this if the portion in parentheses is not to be with the denominator it would specifically noted as such. In that case 48/2*(9+3)

Crazy thing is, focus on shit like this is a waste of time in school. Makes you no money unless you're a math teacher. Veil over your eyes solving pointless equations.

2.............

Parentheses would only "dissolve" as you niggas say if there is a 1 in front of the parentheses. Clearly there is a 2 there.

all this for 1 math problem

ITS 288 YOU DUMB FUCKS! SHiT!

 

[sache]

The answer is 288. Think about it, you are reading this sentence left-to-right...that is how you solve math problems also! Break down the brackets/parenthesis then you handle division/multiplication starting from the left.

some of yall make me feel ashamed

Exactly. you solve what's IN the parentheses first before you move onto the next step. Once nothing INSIDE the brackets can be done anymore, you move to the next step.

You don't multiply what's outside the brackets with what's inside the brackets until the appropriate time. In this case, you can not do it before you divide, as the 48 /2 has priority over it.

Look up distribution rules because they would apply here.

EVERYBODY SAYiNG 2 IS SOFA KING WE TODDED!!!!!!

 

[major pain]

this isn't algebra.

and also, 2 X (4) = (2x1)+(2x3)

so idunt see the difference

It actually is alegbra lol...

You wouldnt see a difference in what you are typing here. Which is why I said consider 2(x+1) vs 2x+1.

 

[major pain]

No, it's the same equation, put it into excel and it will correct it the way I have it written in excel.

It can be interpreted either way. Personally, I would factor the 2 in using the distributive law. Dont hack me bro.

^^^^^^^^^^^

 

[ineedpussy]

whoever said two is right here it is broken down

48/2(9+3)

48/2*12

48/24

2

its that simple.

 

[major pain]

there are no letters being used in place of numbers. this is not algebra

Algebra encompasses more than using variables...

...48/2(9+3) is different from 48/2 * (9+3)

This is where you're incorrect.

Factoring is merely the process of multiplying something into parenthesis or dividing something out of the parenthesis, and parenthesis are used to group terms within.

So using a * as a multiplication symbol would not stop something from factoring into parenthesis.

Let's look at both of these individually:

We start with: 48/2(9+3)
The first thing to notice is that 48 is being divided by 2: 48/2(9+3)
2 goes in to 48 24 times, so now we have: 24(9+3)
Now we can factor 24 into the parenthesis: (24*9+24*3)
Next, we finish multiplying: (216+72)
By adding the two, we get: 288

Now onto the second version: 48/2*(9+3):
Here, the first thing we notice is also that 48 is being divided by 2: 48/2*(9+3)
2 still goes in to 48 24 times, so now we have: 24(9+3)
Now we can multiply 24 into the parenthesis: (24*9+24*3)
Next, we finish multiplying: (216+72)
By adding the two, we get: 288

How about if we start with the parenthesis first?:

We have: 48/2*(9+3) or 48/2(9+3)
This time, we start with the terms in the parenthesis first and add 9 to 3: 48/2(12) or 48/2*(12)
Next, we notice that once again there is a 48 being divided by 2, and we already know what that means: 24(12) or 24*(12)
Now by factoring or multiplying the 24 in we get the product: 288 or 288

So it can be said conclusively that 48/2(9+3) is the same as 48/2 * (9+3) and that both equal 288.

That's it for this edition of Math with fiat.

Niggas saying 288 with heart. It's okay, my sister who's the top engineer in her class missed it too. My younger sister got it right. Me, well I was fucked up for a minute, forget about PEMDAS and didn't bother to answer until I remembered the rules. Just the fact that it's a question make me think this was a trick question.

 

[major pain]

After consulting with an actuary I know. (He has a degree in math). He says he would solve it as 288, but 2 should not be wrong either if this was not a multiple choice problem.

That's it for this addition of Math with fiat.

I understand how you get to that and I'm not saying its wrong, but traditional methods I've been taught would be to distribute first. By doing the division portion of the problem it changes the way you solve the rest.

smh @ niggas just knowing wat PEMDAS stands for and ignoring the rules.
