University of Waterloo doesn't say so: http://cemc2.math.uwaterloo.ca/wired_math/English/lessons/grade9/NSN_INTEG_Gr9.pdf



Once the inside of the brackets is solved, it is purely a multiplication function at that point.

As for purplemath.com, I'd trust the University of Waterloo Faculty of Mathematics instead.

Yes they show multiplication there but they dont show a parentheses as what 2(9+3) is.
That is the point that everyone is missing.

This thread is like watching a huge pile up on the highway. lol

Find another source besides "purplemath" that states that BEDMAS means "Do the inside and outside of brackets first".

BTW, here's another calculator that does it right: http://www.picalc.com/

Its called PEDMAS, its says the very first thing you do is Parentheses.
Find an example saying that in 2(9+3) you don't simplify before solving?
Prove to me that you can put an x anywhere in the equation and be able to solve for it?
 
I'm not even going to spend my time argueing with someone who probably only has gr. 11 math.

LOL, you're batting .000:

Sorry for the written page, I didn't want to type it all out again.

Having posted that, I totally understand what you are saying. However, I find no universal citation that states the distributive property of multiplication takes precedence within BEDMAS (PEDMAS, BODMAS, toe-MAY-toe, toe-MAH-toe).

But when you said 9+x can't be reduced, it can, you can simplify the parentheses through the distributive property before you move on to your division.
How can you be able to remove the parentheses but just skip it and move farther down in PEDMAS?
if it was (x+y) with no number or variable (the 2) associated with it then yes you could skip it and move to division. but it can be simplified which means you should do that first.

I was taught specifically that the B in BEDMAS meant that only the *INSIDE* of the brackets were to be solved first.
After that, the distributive property of multiplication is of *EQUAL* precedence with division, so that's when you begin to solve left-to-right.
 
I was taught that you simplify then solve. So if you can remove parentheses then that should be done first.
because if you solve it the other way then 48/2(9+3) = 48(9+3)/2.
I want to take this to my math professor and see what he says but he would probably slap me for such horribly written problem lol
