Compare contrast multiplication for 1 and 0 and the division for 1 and 0

Rules for dividing by 0 

Rule 1.
0 divided by any number is 0. 

Rule 2. 
You cannot divide by 0. 

Rules for dividing by 1. 

Rule 1. 

any number (except 0) when divided by itself equals 1.

Rule 2. 

any number divided by 1 equals that number. 

The multiplication of 1×0= 0 because anything times one equals that number and anything times zero equals 0. The division of 1 and 0 can't divide.

Iwould think that the correct answer is 8.1
