Answer 2

The expression
`8/0` is undefined.

Solution:

Considering the given equations,

• 
  `-8/ (-8) = 1`
• 
  `-8/8 = (-1)`
• 
  `0/8 =0`
• 
  `8/0` is undefined

The expression is undefined because of the following reason.

Consider the expression
`y =8/ 0`

Here, if y equals 8 divided by 0 then y times 0 should also be 0 but it is not possible except in the situation when both the dividend and divisor is 0.

So, the expression
`8/0` can be stated as undefined.
