No, you're just an idiot. What you saw was probably a character writeup for an NPC. Thus, this character has Negotiate +13 meaning that when you roll a d20, you add 13 to this. There are a number of ways you could achieve this. Say he is skilled in negotiate (+5) and has a charisma of, let's say 18 (+4), (charismas being the ability score, i'm guessing, for this skill). Then he would have to be 8th level d20 + 13 (1/2 level - 4, plus ability score - 4, plus 5 for being trained) if he isn't trained, then with the same stat of 18, he would be 18th level d20 + 13 (1/2 level - 9, plus ability score - 4)
