Jackson owes his sister monica $15. explain the meaning of zero in this situation.

accounting wise, if a value is positive, is an asset, you're above water, +50, you have 50 bucks in your account/pocket.

if a value is negative, is a liability, you're below water, -50, you owe 50 bucks, you're in the hole for 50 clams.

so Jackson owes Monica $15, he's in the hole for 15 bucks, namely his balance with his sister is -15.

if he pays her $1, he owes her 14, so -14 is his balance, let's make a quick table of that

pays her 1 -14

pays her 2-13

pays her 3-12

and so on

pays her 13-2

pays her 150

0 means, he paid her in full.
