Does math really exists!!!
I can’t seem to explain this. You see a shoe that cost $97, but you don’t have money so you decide to borrow $50 from your mother and $50 from your father ($50 + $50)=$100. You then buy the shoe at $97 and the seller gives you $3 as change. You reimburse $1 to your mother and $1 to your father keeping $1 in your pocket. Now you owe your mom $49and your dad $49. ($49+$49)=$98 plus the $1 in your pocket will make a total of $99 . Where is $1? Good reflection.
In my opinion there is no answer to the question.
