It seems like my previous explanation was not enough for u guys, ill try to make it easier for u guys to understand why answer is 2.

So lets think of the number 24; 24 = 18+6 right?

Now lets write "18+6" in parenthesis of 2 which leads us to 2(9+3)

Now if you have completed elementary school you should be able to understand that 2(9+3) is an entire statement and it CANNOT be broken up.

So lets get back to 48/2(9+3)

2(9+3) = 24
48/24 = 2

I hope everyone can uderstand now. In this case Left to right thing doesnt work.
that's not an explanation.
number 24 can be wrote down as a 48/2 which is also part of equatiation.

Also 48/2 can be written down as a 48x0.5

so there should be no talking about priorites in dividing and multiplying.

Do you even understand? 2(9+3) is an entire statement which CANNOT BE BROKEN UP

Edit: Oh and also lets try your way, lets write 24 as 48/2

= 48/48/2
= 48.2/48
= 2
I hope this was simple enough for you.

The distributive property of multiplication CLEARLY states that the 2(9+3) is an entire statement and CANNOT be broken up. 2(9+3) follows the distributive property which can be rewritten as (2*9+2*3). Let me repeat the 2 outside of the parenthesis follows the distributive property of multiplication and must be factored and simplified before performing any other operations on it. You do NOT compute this expression from left to right until you use Algebra to simplify the statement 2(9+3).

So this can be rewritten as:
48 / (2*9 + 2*3).

Which leaves us with.

48 / 24 = 2.

Answer = 2.

Lastly for those using Google or any other online calculator. These do not understand many theorems or properties so you must explicitly explain what you mean. There is a difference between 48 / 2 * (9+3) and 48 / 2(9+3). The first notation reads 48 / 2 * 1(9+3) while the second reads 48 / (2*9+2*3). Be very careful with your signs.

I was too lazy to write it myself so yeah i copy pasted..
