Why are you adding balance as if its separate money?! If you have 10naira and you spend 1naira each day, do you know what the so called "balance" will add up to? 45naira! That's to show you the absurdity of adding money you have before and after spending out of it

In naija no coins so no need to crack brain

D balance column is a log of d remaining funds not a running total of d amount dat was present.. So it's mathematically illogical to add up d balances.... Start d spent amount wit #40 or any oda figures, d added spent nd balance still won't correspond
