Haruto is an uncompromising, courageous, energetic and masculine man, who likes to think that he is pretty tough. But despite a certain coarseness and a triumphant air he is an extremely sensitive individual (although he tends to keep this under control), and a very charming one at that (a quality that he discreetly cultivates).
To subtract in Excel, enter the numbers in a cell using the formula =x-y, complete the same formula using the column and row headings of two different cells, or use the SUM function with negative numbers. Excel does not have a specific SUBTRACT function.
It is a carryover from Lotus 1-2-3, where formulas can be entered as +123+456 instead of =123+456. Excel permits that form as well. It changes the first to the latter.But it changes +A1+B1 to =+A1+B1 for no good reason that I can think of. In any case, there is no reason to use the +A1+B1 or =+A1+B1 convention.+ isn't really necessary, it's the same as =. In older spreadsheet programs, formulas began with +, e.g. +A1+B1. For compatibility, Excel accepts formulas like that, but because formulas must begin with =, it prefixes an =.
