    My maths teacher’s favourite was this one. Noah is sending the animals out from the Ark after arriving on dry ground. “Go forth and multiply” he tells them. But the snakes say “we can’t, we’re adders”. Ok, that was in year 7. Then in year 8, he added the response from Noah, “well, use logs”. That was in the 60s.

    They say "You can't teach an old dog new tricks." In this case, it's true. At 62, I can't get my head to memorise this. Can still do long multiplication with ease. And at speed.

      @GeekProdigyGuy 3 года назад

      it's ok... this "trick" just makes use of a little extra mental math and less writing. it can be faster that way, but you are still doing the same number of digit multiplications and additions.

    As a math teacher im going to tell you that this will confuse the heck out of my students...take about two weeks to teach and then take away from any learning that can happen further. Shortcuts are great, i teach them when i can...but if all you teach is shortcuts then how will someone apply the knowledge to higher learning. I do understand that not a high portion of students will go on to high levels of mathematics, but there are those that might even though they don't think they will yet. The more you ignore fundamentals and focus on fast pathway shortcuts....the harder it is for students to grasp more complicated things. Having said that, this is a fun trick.

    • @einrazer
      @einrazer 3 года назад

      @@youtubeguy8796 fair idea. And that could happen but at that point i would probably defer them to a video (this one perhaps) so that im not cutting into class time with a shortcut rather than something new. I appreciate the fact that you were asking in a respectful way btw. And by no means do i have a problem with someone disagreeing with me. This is my opinion and nothing more and i try to use discourse in the class to teach something.

    • @SteveMasslock
      @SteveMasslock 3 года назад +2

      I agree, this is faster but not necessarily easier . Stick with the way you're taught till it's learned, then on your own learn the short cuts. Faster is not equal to better.

    • @apieceofschmitt
      @apieceofschmitt 3 года назад +1

      It's not a "shortcut" and you are still applying mathematical knowledge. PLACE VALUE. Tens times Hundreds, equals Thousands. How do you teach 8 x 12? ((8x10) + (8x2)) = 80+16=96 --- OR --- 8x2 --> 16 (carry the one, 1_) ---> 8x10= 80 ---> 80 + 1_ = 90 ---> 90 + _6 = 96
      The former applies basic knowledge of addition and multiplication (while still applying place value, but ignoring explaining such). The latter involves knowledge of place value. It requires knowledge of place value and applying such to get to the answer. It's not a substitute for knowledge, it actually requires more knowledge to make the calculation potentially easier and quicker given the numbers involved.

    • @einrazer
      @einrazer 3 года назад +1

      @@apieceofschmitt im not entirely in disagreement with you. However, the way it was expressed was as a faster process. Individuals comment why didnt my teacher go over this. Now, its a great thing to teach, in no way would I argue against that. But the time to learn ratio would be very high and take away from other aspects. I do believe in working on fundamentals with individuals whenever they are needed, but the whole year cant be just fundamentals at a high school level. This is a weighted subject (teaching in general i mean) with a lot of factors that go into what we need to have students do. I get students coming in with numeracy deficiencies that are extreme to put lightly (i teach at high school level). That is not to say they are dumb. They are actually very intelligent. This was just never a priority in their community. So by the time i get through making this make sense to the majority of the students, we will have lost time to other things.

    I’m early! Thank you so much for making this channel! After watching an anime- (The Promised Neverland) I’ve been wanting to get a very high iq this helps me so much!

      I mean.... Getting a very high IQ is probably impossible if your brain is fully developed and you don't have the genes for it. This just made you better at mulitiplication, your IQ didn't increase at all.... Yoi just learnt a method to solving a problem.

      @@septicon1248 Agreed! Every study shows that IQ is mostly genetics; somebody with down syndrome will never have a high IQ no matter how many puzzles you give that person.

      @@praxseb4317 I know, I’m smart enough to know IQ doesn’t raise by being intelligent 😂 It’s mostly about problem-solving. For heck I don’t know my IQ and it could be possible I have the genes Bc my mom has an IQ of 140 and I taught myself division at the age of kindergarten/early first grade. I know I sound like someone who wants to be really smart, and yes I really wanna be! And I’ll work my butt off to get it!

  • @zelda1420
    @zelda1420 3 года назад

    Okay so, basically the way you did this math is that you do the same amount of math all in all, but this method is done more in your head than on paper, and done more all at once, so technically it kind of can be faster, but it's the same amount of math, just a lot crammed together. I see the appeal for those who can and _want_ to do it more quickly by not writing it down and instead doing it in your head, but for those starting multiplication, it's much easier to do it the more traditional method, because it's done more slowly, and then you don't have to remember as much all at once as well. That's the difference.

    • @zelda1420
      @zelda1420 3 года назад

      All in all, this method is the same amount of math, but can be done faster, just because there's more at once and it's much more in your head, less on paper.

    Edit: I just realized, this is just the same thing school teaches you but rephrased!
    Edit 2: you also made this same video a year ago already, but the other way around, I think you may have missed that so that’s why you unlisted it or something.
