The Invention of the Calculator

  I am so sorry for not posting yesterday, but I am posting now. Anyway, you might be thinking, Why are you doing this again??? You already did the abacus, so they are similar. And yes, that's correct, but it's kind of cool, because it relates to another mathematician I blogged about. Blaise Pascal. Pascal first created a sort of calculator. Pascal created it as a way to help his dad handle taxes, not knowing what might become of his invention. Later, Gottfried Leibiniz picked it up, and added the addition, subtraction, multiplication, and divide button on the calculator for easy use. John Napier also added a set of metal rods he called, Napier's Bones, for the multiplication table.  That's basically it. I'll post later today, so do not worry. So, for now, See Ya!
