6^2/2(3)+4

I just want to know if 2 and 3 should be multiplied since 3 is in parenthesis..... a few people I know believe that just because 3 is in parenthesis that it doesn't apply to the PEMDAS rule. Please help.

Response to Kimberly:  It is true that "the 2 and 3 should not be multiplied " because "the 18 and the 3 are multiplied."

Explain why the two and three should not be multiplied. Anything by a parenthesis is to be multiplied when there is no space. I've taken many advanced math classes and I am in college for a degree with a mathematics major. According to all of the rules I know, left to right may prevail, but multiplication is still first. With that being said,  the two is on the other side of the division sign. Therefore it is an variable attached to the parentheses. It's just like the distributive multiplication you face when you get into calculus.

Late answer but.....

If you follow PEMDAS as the gentleman above failed to do you will actually get the correct answer...which isn't 10.


6^2 ÷ 2(3) + 4

36 ÷ 2 * 3 + 4
18 * 3 + 4
54 + 4
58

The parenthesis around the 3 means absolutely nothing in this context other than it being multiplied by the term that proceeds it.  

When you encounter parenthesis you need do what's INSIDE the parenthesis first.  This is the mistake that the gentleman above mine made.

Incorrect.  2(3) should not be multiplied.  As division takes precedence in left to right order for things at the same level.  6^2 = 36.   36/2 = 18.   18*3 = 54   54+4 = 58.   In correct PEMDAS order.
