I saw this on discord and I feel like an idiot but I’m so confused.

*”Question for you guys If I borrow $50 from my mom and $50 from my dad to purchase an object worth $97. Since I would have $3 change I would give one to my mom and one to my dad and keep one my self
So I still owe my mom $49 and my dad $49 that means I owe $98 counting the one I have makes is $99 where did the other $1 go?”*

You owe $98, and you have $1.

You can’t add what you have to what you owe without keeping track of the sign.

Debts are usually expressed as negative, so you HAVE -$98 and you HAVE $1, so if you wanted to add that up, the total would be -98 + 1 = -97. Debt of 97 and object worth 97.
