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!!!!!!
-
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. -

It can be interpreted either way. Personally, I would factor the 2 in using the distributive law. Dont hack me bro. -
-
whoever said two is right here it is broken down
48/2(9+3)
48/2*12
48/24
2
its that simple. -
there are no letters being used in place of numbers. this is not algebra
Algebra encompasses more than using variables... -

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.

? 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 ? 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.

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.

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

Of course it is lol pretty funny. -

Let's look at another method of solving the problem:
We start with: 48/2(9+3)
Now, using the distributive property, we distribute 48/2 into the parenthesis: ((48/2)9+(48/2)3)
Next, we can multiply the distributed term with the terms in the parenthesis: (((48*9/2)9+((48*3)/2))
We can now finish multiplying: ((432/2)+(144/2))
And finally by doing the division by 2 last, we get: (216+72)
After adding, the answer is once again 288
So it can be said conclusively that multiplication and division are commutative operands and that changing the order of the two does not change that answer.
That's it for this edition of Math with fiat.

In this version you are distributing the entire 48/2. Which is the same as 48/2 x (9+3).
Its left to interpretation like I said before. -
Cliff note version.
Is the problem
1. a / b(c + d)
or
2. a / b x (c+d)
First version = 2 as you distribute b into (c + d).
Second verison = 288 as you divide a and b then multiply by the sum of c + d.
As its written, answer = 2. -

...
So it can be said conclusively that there is nothing wrong with distributing fractions, because really, any number can be represented as a fraction.
