Posted by anonymous girl 05/01/2011 12:15 PM48÷2(9+3) = ?

1) 9+3 = 12
2) 2*12 = 24
3) 48 / 24 = 2

PEMDAS aka order of operations. when did we learn that, 2nd grade? the chap who got 288 might need to enroll in some remedial math. 🙂 reply 30 votes report

Posted by anonymous 05/01/2011 03:05 PM 48÷2(9+3) = ? 1) 9+3 = 12 2) 2*…haha, wrong. The answer is 288.

1. 9+3 = 12
2. 48/2(12) = 288

In PEMDAS multiplication and division occur at the same time, from left to right.reply 50 votes report

However, the answer 2 could be justified by the principle of implied multiplication.

For example, consider the problem “2/5x.” If one strictly follows the standard order of operations, the correct interpretation would be “(2/5)*(x).” But many calculators and textbooks state that a higher value of precedence should be placed on implied multiplication than on explicit multiplication: Because “5x” is implied to be “5*x,” it gets higher priority than “2/5.” In this case, “2/5x” would be interpreted as “(2)/(5*x).”

Returning to the original problem, if one utilizes the principles of implied multiplication, then “2(9+3)” gets higher precedence than the explicit “48/2,” and would be solved like this:

48 ÷ 2(9+3)=
48 ÷ 2(12)=
48 ÷ 24=
2

Posted by anonymous 05/01/2011 11:04 PM then why do multiple websites on google claim that it i…On calculator websites, 48÷2(9+3) is not equal to 48/2(9+3) in ambiguous expressions; without additional parentheses, many calculators will default to parsing left to right and use order of operations with division having same precedence as multiplication. In conventional mathematics and most calculators, the expression 48÷2(9+3) is equal to 48/(2(9+3)), and that is most definitely 2.reply 130 votes report
Posted by anonymous 05/02/2011 02:53 AM Wow. It’s 2. Fucking idiots. – Math major…You’re an idiot and not a very good math major if you really think it’s two. Implied multiplication is not considered valid universally therefore the standard PEMDAS ruling would take prescedence resulting in an answer of 288.
