It is undefined
Explanation:The reciprocal of a number is written as inverse of the number
For a number x, reciprocal = 1/x
For number 0, it's inverse if we follow the process above = 1/0
And 1/0 = infinity
But because if we multiply the inverse by its value, it will not give a value of 1
using 1/x forexample: 1/x × x = 1
But 1/0 × 0 ≠ 1
reciprocal of 0 = 1/0
opposite reciprocal of 0 = negative reciprocal of 0
opposite reciprocal of 0 = - 1/0
The result is undefined
