But a fraction is just division.....why would a fraction vs division make any difference?

cause a fraction makes the denominator 2(9+3) which makes the denominator 24,

division makes it 288 cause then itd be done like step said.

the equation uses poor notation, its either or. i argue that its 2 cause to me the / implies its a fraction. so when i read it i read it as 48 over 2(3+9)

written like this,

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

like i said in almost all of my other posts in this thread, it all depends if the slash implies a fraction or if its an actual division sign.

division is no more than a fraction.....they are the same thing.

You're right but it changes how this equation is done

I read it the same way.

They are the same thing....but they are not the same thing.

It does? Math changes by the way you draw the picture?

true. but if you divide 48 by 2 first, then you would be going with the order of operations approach. then you would get you a different answer with order of operations rather then going with PEMDAS.

im getting confused with all this now. :tard:

Pemdas is order of operations

Yes cause it changes how it's acted upon
