    Very informative. Very basic, I like that. Back in school, we had this whole thing where we would break down a larger percentage into smaller parts, then add them together. But that's the opposite of the common phrase "work smarter, not harder". Math, just like many other aspects of life, can be broken down, but not necessarily always into the smallest bits possible.

    Hi mate, I am teaching my child, math, from the Trachtenberg System via Speed Math for Kids 2. In fact I was teaching some of my oppos in the Australian Military, the same back when I could see. See one, Do One, Teach One. Having said that, Ive been watching your videos for some time, and they're wonderful. I am making Playlists for my daughter so that she can watch them in her own time. I however am Disabled, and since my last spinal fusion I have become blind in one eye, and photosensitive, hence where once my problem was needing a 1 inch wide pen, hence my University Math I had to do on Whiteboards (well my last exam anyway), now however, I have to live in Dark Mode, hence Ive had to buy professional UV lights and I am reduced to using the same solution on a black glass whiteboard, still waiting for the second. Its taken me 5 years to get to the point where I have my system in Darkmode, and not everything I can see. So was wondering if you might consider doing your videos in blackboard style again, black background, bright colours.
    Would help me, help her, better. Thank you if you see this, I appreciate all of these videos. I used to be able to deploy a TH-cam invert colours plugin, but its gone now. I cant look at them for any more than a few seconds or without sunglasses which never helps much, its kinda like staring at the sun. Anyway, if you could, Id appreciate it. I dont want to stuff up your work flow so I get it if you cannot. Cheers

    I learn something useful every time I watch one of your videos. Math always came relatively easy to me but I despised the way it was taught in school. There was always this attitude that there was just one way to solve any particular problem and that always seemed to be the most convoluted overly complicated way imaginable.
    Math teacher. "Oh, you need to get to the second floor? You need to start digging a tunnel north, then collect the material you need to make clay. Build a kiln and make bricks. Then you use the bricks to build a temple. Draw people to your temple and create a religion. Form a society around your new religion and build a city. Once there are enough people and enough of an economy for people to specialize start mining metal. Proceed along the technological progression until you develop faster than light travel, then come in from outside the plane of ecliptic and land on the 2nd floor."
    I exaggerate but not nearly as much as you might think.
    My "Why not just walk up the stairs?" questions were never well received.
    I'm always happy for someone to point out another set of stairs (or an escalator).

    • @suzannerhind9307
      @suzannerhind9307 ปีที่แล้ว +1

      I understand what he means now. Instead of working out 5 percent of 18. It is easier to double the percentage to 10 percent and halve the 18 to 9 to get the same answer of 0.9 to then subtract 9 from 0.9 to equal 8.1. Your way is still easier and more efficient though.

    I set my equations up a bit differently, using cross multiplication to achieve my answers. For example in the case of 30% of 61. I set my equation up to read 1/30 is proportional to 61/100, then I cross multiply and divide to obtain my final answer. Thus, (30 x 61) /100 = 1830/100 = 18.3.
