![]() Long division and synthetic division of polynomials. Not my favorite thing to teach, but for $50/hr, I’ll force myself 🤣🤣 Hopefully through word of mouth I’ll pick up more students - It’s definitely easier than substitute teaching!! |

![]() These things are amazing. When I was in school, we had 4 function calculators. Now they solve systems of polynomial equations, graph functions, and do statistical calculations and even can differentiate!! Incredible technology |

![]() Just don't look at your padawans with those "crazy eyes"... |

![]() Apparently it went well… They want to hire me for two sessions a week. Sweeeet! |

![]() Slide rules were available when I was in high school. Although I had a course on them in HS, I was nowhere near proficient. An expected homework assignment for HS senior physics was, “the next chapter, every other problem at the end”, - “AND, the last two”, Chrome Dome seemed to get a kick out of emphasizing as we were completing the last physics class of a 2 week in school period at Patterson Co-op HS. Them last two problems typically required pages of hand calculations, with all work submitted if you wanted any credit for your effort. A demonstrated attempt on the last 2 was apparently among the minimum requirement's for a “B”. Not turning in ones homework was guaranteed to get ya the promised “F”, and no senior physics credit. The class size was down about 50% by the end of the 1st semester. A four function hand held calculator of the type that would be widely available about two decades later would have been great! |

![]() Now fir $85, you can get a graphic calculator that gas 10 tines more computing power than the Apollo missions to the moon. I just missed slide rules by about 5 years |

![]() My youngest step son was using TI graphic calculators in mid 90’s HS, they are extremely capable, and reasonably priced. The miniaturization of electronics, especially digital electronics, thanks near solely to the invention of the transistor, must surly place the transistor as the singularly most significant of all human inventions. |

![]() I could be remembering the price wrong, but Im sure it wasn’t $200 Yeah I was 12 ish |

![]() There ain't no-way you got a hand-held solid state calculator for $30.00 in 1971, Brother. I bought one of the early hand -held calculators somewhere around 1970 for over $200.00 and it was "loaded" with four-function capability (+, -, x and divide) and a constant. Yea it was a faster than doing the work on a slide rule (also more accurate than a slide rule), a piece of paper or an abacus but that's about it. See old Smithsonian Institute calculator collection (no prices shown). americanhistory.si.edu. And Jon: Do I ever remember our ass-hole, "Chrome-dome" physics teacher. I also remember his large wall-hanging slide rule that he could flip-over in a few seconds to apply information on the reverse side --- of course he never gave us enough time for us students to figure-out what he was doing with it. |

![]() My dad continued doing sums with stylus and chain. In my hot little hand as I type is a TI-30X A. LCD instead of LED. I bought it last year for around $12. They added a cube root button, I just noticed, though y^x and y^(1/x) [xth root of y] remain. I think it has a few extra registers, but I’m not sure. The old one had good memory too. |

|
![]() But whatever 🙂 Now I use a TI-85 graphic calculator that cost $85 6 years ago. |

![]() Word of mouth and substituting is best. I’ve used Craig’s List, but it’s hit or miss. |

![]() Not far getter 🤣 |
