stana · Answer

is 6 the one raised to 2 or 3/6 itself?

welshfella · Answer

Yes  this  question can be interpreted in a few different ways.

mathmale · Answer

My thought exactly.  Please, reduce the ambiguity here by using parentheses to indicate which operations are to be done first.

mathmale · Answer

I would write "3 over 6 to the power of 2" as (3/6)^2.  This indicates that the operation 3/6 must be done first, because 3/6 appears within parentheses.

mathmale · Answer

The "+ 7 × 4 − 5" part is less ambiguous, because PEMDAS (order of operations rules) state that multiplication must be performed before subtraction.
