Question about Canon P23-DH Calculator
My "=" sign is not working when adding or subtracting numbers to show the total. I have to always press "+" button for that? why oh why?
Because this is an adding machine you would use the total button (*) not the = for ading and subtracting the = is only used in multiplcation and division
