It feels natural to anyone who understands binary numbers. Every odd number in binary will have the last bit as 1. Just like in the decimal system, every number that is a multiple of 10 will has the last digit as 0. If you want to see if a number is a multiple of ten, I guess you could do a mod 10 of the number and see if the remainder is 0. But if you understand the decimal system, you would just naturally check if the last digit is 0. |
