@jhonyy9 pls help me

Answer 2

I assume blue arrows are deposits, and red arrows are withdrawals...
"deposited $35" and "withdrew $50"

So blue arrow going up 35 units from 0, and red arrow going down 50 units from 35.
Why?
The blue arrow goes up since you're adding money. But the red arrow goes down because you remove money.
