This is not true, see above or plug both into a calculator exactly as shown above.

The real engineering world doesn't use that division symbol. I do structural calculations all day long, verified by computer, and checked by my superiors. I don't know what to tell you if you don't believe me.

Can't you distribute whenever you want in a problem?

I hope I never use any of the structures you design.

You probably already have.

So are some mathematicians now arguing multiplication should take precedence over division? I did not see that in school as of 2010.
Sounds really stupid to me. Mainly because division IS multiplication.
48÷2(9+3) simplifies to 48÷2×12.
48÷2×12 is the exact same as (48/1)x(1/2)x(12/1)
Which is 48x.5x12.
This will always equal 288. If you disagree, sorry but you're... dumb.

Holy shite, please let us know where you're employed. If you work where I do, I'll forward this thread to the department manager to ensure you don't stamp anything in the future.

Wolfram went beyond the division and multiplication argument and split multiplication into two parts at some point. They have since back pedaled.
I'm back to leaning towards both answers are correct.

Wolfram Alpha changed in early 2013 to treat implied multiplication the same as explicit multiplication (formerly, implied multiplication without parentheses was assumed to bind more strongly than explicit multiplication
I'm back to leaning towards both answers are correct.

Why are people arguing an indisputable fact? The answer is 288. It's not an opinion.

I'll make you a deal. Show me anywhere in the AISC SCM or ACI 318, or NDS where the ÷ symbol is used, and I will tell you a project around New Orleans that I have worked on. The problem is written terribly, hence 8+ pages of discussion.

That giant calculator got an actual division symbol on it or does it only have the "/" Evidently it can make a difference and so can "implied" multiplication.

Except it completely disregards the order of operations...
