Question

When any natural number is divided by $10$ what is the sum of all possible remainders?

Answer 1

Any natural number is divided by 10 and the sum of all possible remainders.

Natural numbers are a part of a real number from $1$ to $\infty$. So any natural number is divided by 10.

The possible remainder when any natural number is divided by 10 are :

$0,1,2,3,4,5,6,7,8,9$

Therefore, the sum of all possible remainders is:

$0+1+2+3+4+5+6+7+8+9=45$

Hence, the possible value is $45$ .
