How to Calculate Grain Taxes

This is sort of a paper calculator developed a dedicated equation, right? This one I stole from a guy named Chris Stieker, who has numerous videos on the subject as well as early adding machines. So it's just things with people counting back in the day. Grain taxes. Taxes on grain. Money, materials, you know, anything that needed to be counted. And like days and then that leads you into sort of calendars. Because I suppose all this and now it's kind of done by computers.
