BellaOnline Forums Education Math 6÷2(1+2)=?

Time I dust off this thread & provide the answer as derived by two college math professors (One is a very close frind of mine & a retired Math PhD) er.jacob89 breaks it down above by doing the parened operation first...

*E*: left to right is the precedence for mult/div 6�2*3. Correct answer is 3*3 or 9.
*G*: Brad - *E* stated it correctly (no big surprise to either *E* or me). Math follows certain conventions and the left to right is one of them. I learned it (way back when) as : Add or multiply or divide, then add or subtract. In case of a tie go left to right. The Please Excuse My Dear Aunt Sally tells you to do what is in the parentheses first, then exponents then multiply or divide, then add or subtract (in case of a tie go left to right).

I'll now rest my case with an answer of NINE (9)

I so agree! Good job, Beetle. You have settled it once and for all. Yeaaaaah!!!!

Agree with Beetlemess:)

Beetle, that's how I teach it. Your explanation a long time ago was brilliant. That's when I started reading your posts; it was so elegantly written.

Hallejuah!

wooooo hoooo!!!! I always had faith in you, Beetle.

[quote=Lisa - Fiction Writing]The correct answer is 1. The second way you worked out the equation was correct, Beetle. [/quote] Yes It is As the ( have most prior then multiplication , then Division .

Fully agree that the parened (1+2) operation is to be handled initially.
Yet, Multiplication does not have a priority over Division and are conducted mutually in left-to-right ordered process, before any Addition/Subtraction... as Division is merely multiplication of the value's inverse.
