Although promising the magazine raises one question:
63 = 2^6-1
To be accurate...
eh? The exponentiation operator has a higher precedence than the subtraction operator. The parenthesis are redundant.
Assuming a positive inflation, isn't the 2 year cheaper, unless the inflation is less than 1 euro a year for a 63 euro charge?
Only if interest rates are less than the inflation rate. You have the 63 euros sitting around in your bank for a year. Also, you might decide that the magazine is crap and not subscribe anymore.

Sure, parenthesis are a best practice, but they still aren't necessary.
