Q:

Is it "correct" to do a binary mathematical operation by converting to decimal?

Is it considered correct in order to do a binary or hexadecimal operation to convert to decimal, do the operation, and then convert back to the original numeral system?
Is the above not advised?
Is the above frawned upon?
The context is a (first year) Programming Open University Course and the guide (in lack of a better word to describe him) is delaying my enquiry.

A:

Yes, it's generally correct. Numbers are numbers, no matter how you represent them as text. Note that binary, decimal, and hexadecimal are all text representations of numbers.
