say its january 1st, you have $50 in your bank account then you spend money, it would look like -$5.50 for example but if it looks like $5.50, you added that money.
so you have $50 and take away $35.35
50-35.35=14.65
you now have 14.65 then spend 125.65
14.65-125.65=-111
now you have -$111 and then you add $78.95 to your account
-$111+$78.95=-$32.05
you have -$32.05 then spend $95.15
-$32.05-$95.15=-$63.10
now you have -$63.10 then add $212.50
-$63.10+212.50=149.40
so now at the end of the month you have $149.40.
i really hope this helps!:)
