If you can remember all that, you can remember your times tables.
People will start calling me psycho if I start rotating fingers and calculate while I'm shopping groceries 🙄🙄
Its better to memorize the multiplication table
Soon as he said “turn your hands” I lost him
Much easier to just remember the tables. Once the numbers have penetrated your braincells, they usually stay there for the rest of your life.
thank you for this tutorial. when i was young my dad thought me this multiplication using my fingers. i totally forgot it and was not able to ask my dad again. now he is gone, you reminded me of my dad. thank you so much that now i know how to multiply again using fingers.
I didn’t know this was a thing. I only knew about the 9 times tables with the hands
im watching this is 2024 ;-; edit: omg thanks for all the likes and replys!!!
You better memorize it.
Wow, this is a wonderful tool to teach kids, thank you. For those of you who say "just memorize": memorization isn't the best method to teach math, and the sheer lack of adults who still do not fully understand multiplication proves that this older method has failed many generations. Reason for this is that there is a massive diversity in how people recall learned knowledge. For some, it is very visual but the majority of people it is hands on. So tools like this are actually wonderful methods in getting kids to begin memorizing the times tables. Telling a child to sit down and stare at a foreign piece of paper for hours in hope that they'll recall all of the information is illogical. Now having the child use the two tools they were born with to play with math, become more confident in their answers, and to never feel stuck is a wonderful alternative. And if you think this isn't a tool for memorization, then how did you ever learn how to play a sport, drive a car, or perform some level of physical activity that required physical memory? Most musicians will tell you that a great amount of their skill and talent is more subconscious memory (physical memory)
I feel like this is more complicated and time-consuming than just memorizing the multiplication table. You'll save more time in exams and can even save from being looked at strangely by your teacher.
im in 6th grade and i cant do 6, 7, 8, 12 and 13th times tables :(
I really like this. Well done. Anything that helps kids learn their times/multiplication table is awesome. I do think that the problem with this method though is that if you aren't good at doing the addition in your head, you will get it wrong sometimes. Best to use this method to the point where you eventually don't need it. But, for many kids and adults, they might always need it, so it is great. Well done.
First step is 10((a-5) + (b-5)) = 10a + 10b - 100 Second step is (10-a)(10-b) = 100 - 10a - 10b + ab Add them together, you're left with only the ab term, which is what you were trying to find. :)
No but thks I m ok with my old method . It's simple
Hi I’m 10 years old! Because of you I finally know my times tables. Thank you soo much :)
lol my dad taught me this and I showed this to everyone in my school and they seemed impressed
Sorry but this is WAY MORE than a little trick, this is AMAZING!! I’m a grown adult and struggled in math as a kid and never learned my multiplication facts. This seriously seems like it should be taught in every school on Day 1 and also be on the news with how amazing this is. Thank you so so so so much!
lmao i cant even memorize my own multpilication table 😂
If you have to use fingers to remember your times tables, you aren’t remembering your times tables.
