      True, in my opinion, teachers and professors take that long on purpose like they could have finished earlier, but they decide to finish nearly at the exact time because of institutional guidelines that they have to follow including the pay per hour rule.

    I appreciate that you take the time to solve the equations without using a calculator. My chemistry professor isn’t that cruel, but my calculus professor IS. All these little tricks to combining very large numbers without a calculator has been a lifesaver! You and Professor Leonard have gotten me through my last semester as an undergrad.

  • @cassandra-lynnecowley6475
    @cassandra-lynnecowley6475 6 ปีที่แล้ว +20

    Just an FYI for you, towards the end of your video when you have the equation (-393) + 2(-286) - (-785) ..... You calculated that 2*-286 was 576.. but it is actually 572. which would make the actual answer to the equation be 180. just thought i would mention.... LOVED the video though, really helped me better understand.. I have a midterm on Saturday .. here to hoping I pass.
