...wise it's 0. OR is 1 if one or both of its inputs are 1, otherwise it's 0. XOR is 1 only if exactly one of its inputs are 1, otherwise it's 0. NOT is 1 only if its input is 0, otherwise it's 0. These can often be best shown as truth tables. Input possibilities are on the top and left, the resulta...
