Very dumb question:

What is the order of operations in the following:

PEMDAS a/b+c = a : b + c (where ":" is the division symbol)

7/1+6 or 7:1+6

in the example below is it 1 or 13?

    Standard order convention would have it be $13$. You would need $7/(1+6)$ or $7\colon(1+6)$ for it to be interpreted as $1$.2012-06-29

    If you are entering things into a computer program, you need to know the order of precedence that it uses. If you are communicating with a human, if in doubt use parentheses.2012-06-29
