2 lulz

Edit:
So it comes down to whether you see it as
[48/2] x [12]
or
48 / (2(9+3))

That was punny.

Um...I'll vouch for 288. Because, you know, if it was to be 2, then it should've been written as 48/(2*(9+3)).

Brackets are important.

It depends on how you interpret the implicit multiplication with the brackets. In the Casio 991fx, entering as it's written in the title gives 2 and adding a '*' after the 2 gives 288.

Why would this be a debate o.O. It's like what, grade 8 math or something . BEDMAS! So the brackets then the multiplication in the order they appear i.e. 288

Hmmm it might actually be 288 because if BEDMAS were to be followed:

= 48÷2(9+3) Brackets
= 48÷2(12) (we'll go from left to right)
= 24(12)
= 288

Am I wrong in assuming that we read (and thus should calculate) from left to right?

Wolfram Alpha says 288.

We must trust in the holy Wolfram.

Because its an ambiguous equation

48÷[2*(9+3)] = 2.

or 288 if you dont think of it as a single term

This. Yup, ÷ = x but you work left to right.

2(9+3) tends to imply (2(9+3)), but based on the formal rules of mathematics it should be 288, right?

Definitely 288.

Division comes first before multiplication.

Division and multiplication are interchangable, just as addition and subtraction are ( B E DM AS)
