April 12th, 2011 06:32 PM #7assuming i remember my high school math correctly, answer is 2.
simplify 2(9+3) first. then use the answer as the divisor of 48.
always remember the MDAS and BODMAS rule when it comes to order of operations.

April 12th, 2011 06:38 PM #8The answer is 2. Compute first the ones inside the parenthesis.
48 / 2(9+3)
48 / 2(12)
48 / 24
= 2.

April 12th, 2011 07:57 PM #15the thing is you *should* follow MDAS rule however, (9+3) is *not* part of the divisor since it's not (2(9+3))
Damn, son! Where'd you find this?

April 12th, 2011 07:57 PM #16^^ yes. and it only applies when there is no parenthesis. otherwise simplify the one inside the parenthesis first.
but the answer is still 2.

April 12th, 2011 08:08 PM #17^yes, there's no parenthesis therefore you should not include it in the divisor:
48 x (9+3) = 288

April 12th, 2011 08:26 PM #20I created a simple script to see what the result is.
copy-paste into a text file, name it test.html.
Then, open the file with a browser.
<html>
<body>
<script>
document.write("48/2(9+3) = " + 48/2*(9+3));
</script>
</body>
</html>
48÷2(9+3) is simply 48÷2×(9+3)
The rule in algebra is that operations follow the MDAS rule from left to right, with the parenthesis changing the precedence order. So, 48÷2 gets operated on first. The result is then multiplied to the result of (9+3) since the parenthesis around 9 and 3 indicate the summation must be done first.
This is just like
a÷bc
the above is NOT a÷(bc), because multiplication and division have the same precedence.
a÷bc is just (a÷b)c
