Is a decimal number system the best to grasp mathematics?

the result of any multiplication by $5$ will always end with a $0$ or a $5$

Similar properties apply to a multiple of d in base b, if d divides b.


a number is divisible by $3$ if the sum of its digits is divisible by $3$

Similar properties apply to a multiple of d in base b, if d divides $b-1$.


Not at all. The concept of using 10 as a baseline probably grew out of the practice of calculating using one's fingers

But all kinds of number systems have been used in place of the decimal system and with relative successes. For instance, our computers expressly use the binary system, and switch to hexadecimal for representation purposes.

Decimal system only remains that important to us mathematically, because we have had a history of using 10 as a base (for reasons explained on the wiki and elsewhere). So naturally, any computation we do using the decimal system seems like a breeze. I am sure similar rules like those for the digits 3 and 5 do exist for numbers in other base systems.
