Help these stupid skaters solve this problem, the answer is clearly 2.

>> No.2850284

the fucking two applies to the bracket and then therefore can only affect the 48 once it has been multiplied into the bracket. You cant divide by 2 then multiply by twelve thats completely incorrect.

Everyone in this thread needs to learn how to use an obelus (the division sign)

When you use an obelus, it is the same rules as using * for multiplication, except with division. You take the number on the left and divide it by the number on the right. It follows standard order of operations, so it's on the same level as multiplication.

So, the problem is:

48(obelus)2*(9+3) -parentheses first
=48(obelus)2*12 -at this point you just work it left to right
=24*12
=288

Problem solved, that distributive property stuff is bullshit. Numbers next to parentheses do not receiver higher preference in the order of operations than other multiplications.

Mathprof here. I use this equation at the beginning of every year to distinguish the idiots in my class. If they say 288 they get the boot

Cool story bro. Post proof that it's not 288 or shut up, because order of operations and proper use of an obelus say it's 288. As do numerous calculators.

Fuck me for feeding the trolls, but I've offered a proof of a problem which you have said is wrong. You have then failed to prove my solution is wrong.

You need to lrn2math and offer evidence to support your claim.

>> No.2850705

ok retards. using distributive property for multiplication..
the equation:
48/2(9+3) becomes,
48/(2*9+2*3) which becomes,,,
48/(18+6) thus...
48/24 which equals...
2!!!!!!!!!!!

>> No.2850718

>>2850705
You're ignoring the fact that by the order of operations you must first divide 48 by 2 if you are going to distribute.

>> No.2850726

Change it to a multiplication only problem and you faggots will clearly see that it is 288.

48*.5*(9+3) = 288
