# XOR

This is interesting because you can use XOR again to get one of the LHS components.

Let’s use `^`

to denote XOR.

Lets say we have `a ^ b = c`

. We can reverse it to get back a: `a = c ^ b`

.

XOR | a | b | c | c ^ b | |—|—|—|—––| | 1 | 0 | 1 | 1 | | 0 | 1 | 1 | 0 | | 0 | 0 | 0 | 0 | | 1 | 1 | 0 | 1 |
