It depends on if you want to reverse the operands or allow the scribbles to impart useful information.

Teacher Fiance tied me up, ball gagged me, and spanked me until I admitted it was 58.

The importance of operating on the same page as everyone else has real significance. But the decision on how to read and interpret the order is arbitrary. The communicative property is a reflection of mathatical truth in the language construct we have built to express ideas.

Poorly written. Yikes.

Anyway.

Here is an article explaining the order of operations.

58 - CPSC/MGMT minor (started as MATH minor, but eng calc III convinced me to say "screw this").

But let's make it more interesting.....

6^2 / 2x + 4.....solve for f(3)

I love seeing these, I always just shake my head wondering how the hell we have so many people out there that don't know basic math.

Division IS multiplication. 1 X 10 is exactly the same thing as 1 / 0.10. It's the same operation. Therefore, saying "multiply before you divide" is like saying "multiply before you multiply".
