48÷2(9+3) = ?

The calculator obviously simplified 48/2(9+3) to (48/2)*(9+3) and used SOOO to simplify the equation.

48 ÷ 2 (9+3)
24 (12)
24 x 12

= 288

when there's a bracket the values multiply

SOOO vs Pemdas
~ SOOO will basically simplify it to 288.
~ PEMDAS will basically simplify to 2.

The resulting answer between both differs due to dissimilar order of mathematical processes.
~ Division is applied before multiplication in SOOO.
~ Multiplication is applied before division in PEMDAS

They're the same thing, and multiplication and division have the same priority. If they're the two operands to do in a sum, then you just work from left to right. To get the answer 2, you'd have to force the multiplication first and do 48/(2(9+3)).

And calculators that have a stack i.e. graphic calculators will give the result 288. Other calculators without a stack will give the answer 2. I gave an example of it a couple of pages back.

No disrespect intended Everlong, but the rule, in PEMDAS, is not multipication first, multipication and division are equal in status. What you do is simply start from the left and go to the right.

That's what I said, and it's what I've always been saying that multiplication and division have the same precedence.

Just seen my last post has the quote messed up. I've fixed it, so it should look clearer to what I said.

I just do the stuff in parenthesis first, then all the multiplication/division operations from left to right, like they taught me in college. :P

288

I hope there's no hard feelings Everlong. :)

None at all :)

Multiplication doesn't have precedence over division though and vice versa. If they're the only two operands left in the sum, then you simply just work left to right and in this case it would be divide then multiply, hence you get 288.

You get the A+.

Microsoft Math bears this out, as does Professor M. at CSU.

If you still don't believe it you must be using a Mac.

MS Math FTW. LOL at using a Mac XD XD XD
