Is math.
Using poor notation when writing a sum doesn't make it hard >:O
The answer isn't 2, but 288.
Since multiplication and division operations are of the same priority, we must do them from left to right:
1. Parentheses (always first) : 48/2(9+3) = 48/2*12
2. Division : 48/2*12 = 24*12
3. Multiplication : 24*12 = 288
Nothing much to say.
I like dragons! They're the center of my life! I'll never forget them...
but the answer IS 2, lol...
2 * 3(6+6)
the 3 takes precidence, and should be done with the brackets before multiplying it with 2.
According to Bimdas as I was taught; (Ed. or as my memory retained?)
48/2(9+3) (Brackets first)
=48/ (2x12) - added brackets for ease of reading. (No inidicies, thus multiplication)
=48/24 (Division, but no addition or subtraction, so...)
=2
I was always taught that Bimdas was followed to the letter (damn I'm funny) but I have googled it and Dragonslover's point, that multiplication and division have equal priority and thus left to right is followed, was immediately backed up.
My mother is a maths teacher, though, so I might ask her tomorrow morning if it 'tis equal or weighted priority. But the catch there is different countries use different stuff.
Edit: I can confirm that there is no priority, so it is not weighted as I believed.So I cede to Mothrayas and Dragonslover.
