You don't need to rotate your fingers, u can just to shut your fingers down and let the others, and u can calculate it by adding the finger that u shut with the other side and multiple the finger that u up for example : 6*7 is shut one finger on the right or left and shut two fingers on the other side and each finger that you shut are equal to ten and the rest is u can just adding them and multiple the the finger that u open and each finger that u open are equal to one
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 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.
This was a help? By what stretch of the imagination is this considered helpful? This isn’t teaching the kids to memorize anything - it’s teaching them to rely upon woke math instead of memorizing - And yet it still requires one to memorize your times tables.
Speaking as a prior US Navy nuclear engineer who now formally teaches elementary, high school and university sciences and advanced mathematics, and whose son is now working on division with fractions (at only 5 years old - while seeking to complete 3rd grade through the University of Oxford)... The advantage to this technique is that it both allows younger children an easy access to multiplication through kinesthetic learning, while at the same time providing a form of visual model they can use anywhere - immediately. Rote memorization of the multiplication table is useful for many, but the data from published studies suggests not all, and actually much fewer than some would suspect. Few actually progress into careers with greater mathematical requirements, and this is largely because their understanding at an earlier level becomes tied to pure memorization of a table without understanding behind it, leading to frustrations and a growing sense of helplessness/hopelessness later. Ultimately, whether using fingers or the multiplication table, the end goal is automaticity. Both *can* yield this end goal, but those exposed to a functional way to derive results at an earlier age (the "anyone can do it effect') find improved sense of self-esteem that goes with the learning, and the process more solidly drives the learning into long-term.
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.
@@ultravioletpisces3666 tbh this should be memorized when you step into the elementary stage. Well, I can understand that some people really have slow comprehension of numbers but are good at other things.
I know what that is. It became helpful to me when I'm still not that good in Math. Now, I don't need that. In fact, I've been to Math Competitions and won. This is a proof that people can change. People can improve if they practice. This is an inspiration. But the single table in my mind still remain. The 9 times table in my mind. When you multiply something by 9, for example 9x6, decrease the factor other than 9 by 1 then multiply it by 10 so it will be 50. Then add the difference between 10 and the number other than the 9 so it would be 4. 50+4=54. It may seems long to you but it only takes me only 3 seconds to solve them. 9x6=54 Another example, 9x8=? 👆 8-1=7x10=70 }>_ Add these 10-8=2 }> two. 70+2=72 Thus, 9x8=72 From 8 to 70. The difference between 10 and 8. Add them together. Did you get it? Now, answer this. 9x7=?
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've been using it since grade 4 back in 2000. Can't believe it's been 23 years already. God bless Mr. Auwal my lesson teacher who taught me the trick. Kano, Nigeria.
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!
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. :)
For everyone saying, "Just memorize the times tables," that’s great if you have the type of memory that works to quickly memorize by rote. Not everyone's brain works the same. Some people take longer to memorize what can seem like dozens and dozens of random numbers. So what is wrong with having a little trick to get by, if that works for you? By repeatedly using this method, students will get the right answer, which will help solidify it in their brains to the point at which it does become rote.
You just changed my 3rd graders life. Honestly was having the most difficult time before seeing this video! It took him all of 10’min to memorize this formula!!
when I realised multiplying was an actual cheat to counting all 100 tiles on house roof I was hooked. made so much sense to just count up rows and columns!
Im a 9th grader and I was really struggling in multiplication since 3rd grade, it was hard for me to remember but this video LITERALLY MADE ME SO HAPPY ITS AN AMAZING TRICK I WOULD DEFINITELY RECOMMEND SOMEONE WHO HAD PROBLEMS WITH MULTIPLICATION ✨✨
I think thats a brilliant tip. Ive always struggled to remember how to do times tablesand now i know it! Thankyou for sharing!. I can pass this on to my kids now
@@user-zy4eh9ps2g You get 3 on the the bottom first digit then on the top 3x4=12 You take the 1 on the 12 and give it to 3 so 3+1=4 You join the 4 and 2 together and you get 42
learned this when i was in elementary and watching this video refreshes my memory. This trick is really easy to learn. Memorization wasnt my thing before.
Thank you!!! I googled easiest way to learn multiplication for my 3rd grader and I came across this very useful video!!!! I’ve been out of school for a very long time so this helped me soooo much!!! 🤯
Please do!! I am seeing all of these negative comments that it’s “better to memorize them”. Well sure it is I bet if you can. I’m epileptic, seizures have hit the short turn memory a few too many times and I struggled horribly with math in school and wish I would have known this.
I have a calculus exam tomorrow and this actually SAVED MY LIFE. No fr🥲considering no calculators are allowed...Kinda wish I knew this back in 5th grade or so, but we move lol

wow this really helped out. and i never knew this method although i know a much easier method for the 9x table example 9x8 open your hands then fold one finger (which is the number your going to multiply) count how many fingers in the left of the folded finger then thats the ones place then in the right side its the tens place so the answer is 72 *sorry for long explanation*
I memorized the Times Table when I was in the 5th grade. They were always printed on the notebooks that you buy to write in. You can't forget it because you keep using it over and over again. I'm 89 years old and the Times Table are branded on my forehead. I can't see it, but my brains can.
"It's a pretty neat trick." Nah. For someone who easily memorized the multiplication table through number series, this one is hella complicated that it's my first time learning how the finger trick everyone uses works.
Forget all these tricks, just make the effort to learn the tables, after that lots of maths becomes much easier. You need to instantly know your tables to spot factors etc.
I was taught to memorise this whole thing as a kid, to the point if I was wrong, I would be bawling my eyes out. and to be honest, that seem easier at this point. But this method is very easy, i reccomend it to children who are still learning multiplication
@@Faithdced I found it to be very surprising. According to google, 3rd grade is age 8 and 9 years. Children should know the times table properly by 8 years old. This young person is having to use tricks.
For some people who have trouble with nine's tables. 9×0=0 9×1=9 9×2=18 9×3=27 9×4=36 9×5=45 9×6=54 9×7=63 9×8=72 9×9=81 9×10=90 Notice? In the ones places in all of the products, it starts from subtracting 1. In the tens place, it's adding 1. ------------------------------------------------------ 9×11=99 9×12=108 9×13=117 9×13=126 9×14=135 9×15=144 9×16=153 ------------------------------------------------------ Not sure if these ones are correct, but you should get the idea.
You can use your fingers for this. Just put one finger down. The fingers to the left are the tens place and to the right the ones. An oldie but a goodie.
To do the 9 times table simply hold all 10 fingers out and count along the number you want to multiply by and then the numbers before are 10s and the ones after are units so for example 9 x 3. Count 3 fingers along, flip it down 2 before and 7 after the finger makes 27. 9 x 7. Count along flip down the seventh 6 before 3 after = 63.
Cool trick! And yeah, as many of the commenters have pointed out, it's not really useful if you've memorised your times tables, but tricks like this are good for those who are learning them. For more advanced math nerds, they make for a good puzzle: why does this trick work?
I don’t know what to think or do because you made my life easier I always wanted to achieve my goal and I don’t know I love you so much thank you so much ❤️🔥❤️🔥❤️🔥❤️🔥
This is pretty useful for me even though im lazy to memorize it is actually a great trick but I hope there is also a finger trick like this but you can multiply the 6-10 with other lower numbers like 5-1
Actually this is easier if you just reverse the order of numbers. Little finger = 6 / ring finger = 7 / middle = 8 / index finger = 9 And use the same technique. It was as easy as clasping your palms. You don't have to rotate your hands. Other people might not even notice what you're doing. I know this since Elementary grades. I forgot who taught me this. Ex. 6 x 9 Little finger touches Index finger, count the fingers below together with the Little and Index (5) = 50 (fingers below always x 10) count remaining fingers of the Left hand multiply it to remaining finger in the right hand. (4 x 1 = 4) answer = 54
Memorizing of math tables is easy and boring after you memorized all the tables, but his tricks is easy way how multiplication of number works....Good Job
THX FOR TEACHING ME BECAUSE EVERY NIGHT I HAVE TO STUDY TIME TABLES AND TONIGHT I HAVE TO DO 7 TIME TABLE AND I KEEP FORGETTING IT SO I SEACHED HOW TO REMEMBER TIME TABLES AND YOU POP UP SO THXXXXX!
I wanna die badly.I have a math test tomorrow and I don’t even know my 6,7,8,12.AND MY WHOLE ENTIRE CLASS BE LIKE “ooohhhhh 67x8 is thaaatttt....”and I’m here like “Alina,what’s 6x7?”
It worked so well, because you saw that dude nailed to the plus sign at the front of the classroom, and it subconsciously made you fear that it would happen to you, if you didn't pass math.
