[FIXED] How to declare the "b variable" as negative?

Issue

I'm trying to declare the value as a negative number, but I'm not quite sure how to do this.

pragma solidity ^0.8.4;

contract Contract {
    int8 public a;
    int8 public b;
    int16 public difference = a - -b;
}

Solution

You can't give a negative number to uint, instead you should use int.

What you are looking for:

contract Contract {
    int8 public a = 3;
    int8 public b = -3;
    int16 public difference = a - -b;
    //If it did not work, change above line to this:
    //int16 public difference = a - b;
}
