-When using the signed hexadecimal number system in programming (such as [[68000]] assembly), the values '''$81''' to '''$FF''' are interpreted as '''-$7F''' to '''-$01''' respectively. This is simpler than actually prefixing a number with the minus symbol "-".
-Conversely, the '''unsigned''' number system has no negatives. So '''$81''' is read simply as '''$81'''.
