Yes, but computing an integer into it's reciprocal (which is what you're doing in decimal) is the computation that makes it more complex, you're just offloading that from the machine to your head. Try doing this with x/31, show me the operation to convert 31 into it's reciprocal in decimal and you'll see where the complexity lies.

I assume for most programming languages there is no speed difference in writing
