We had to do all our math the long way. With pencil, paper, and erasers. Does any one know what an eraser is now? Sure, it took time. Then we progressed... the calculator. How fast and easy it was once you figured out the buttons. And the funny little words like lol or oil that you could make it spell. Well, for these courses I was doing the long hand, and when there was power in my phone, the phone calculator. I looked up calculator on my start button and found one that was close to my phone. Wasn't any good for square roots so got rid of it. Then I looked up scientific calculator....OMG! Who needs a pencil? I found the most amazing calculator for my computer. It does everything, from computing, to 2 3 D graphing, triangles, the endless possibilities. All I can say is.... Where is the off/on switch?
Back to studying
It is called Microsoft Mathematics.. for those interested. Free download calculator from microsoft. And if you do happen to download and understand how to use, please post utubes on the various keys and formulas. Haven't figured out how to do standard deviation on the calcuator yet.
