 Hi, this is Chico. What I wanted to do in this video was show you a couple of tricks that I've learned of how to learn your multiplication table. A couple of hand tricks anyway. Now, the first one is a trick that I've known for a long time and it works for multiplying 9 by any single digit number and the second trick is something that I just learned like a couple of weeks ago from a student that helps you remember how to multiply 6, 7, 8, 9, 10 together. Okay. Now, the first trick is pretty simple. It's really easy. It's this trick that I've had in my toolbox for a very long time. What you end up doing is if you hold up both your hands like this, what you do is starting from your pinky either this one or this one. I usually I'm right-handed so I start with my right hand. So what you do is you take your pinky you go 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 and those are your 10 digit numbers, right? Your 10 fingers and if you want to multiply any of these numbers with 9, what you end up doing is going down the row. So let's say we want to multiply 3 times 9, right? So we're gonna go 1, 2, 3. You pull down the third finger, right? And 3 times 9 is 27, right? If you're looking at it first person, it comes out as 2 and a 7 which is 27, right? And this works for all 10 numbers. So let's say you want to multiply 5, 5 times 9, right? We go 1, 2, 3, 4, 5. We pull this one back. 5 times 9 is 45, right? It's pretty simple, pretty cute and really easy to do and everyone picks it up right away, okay? Now this this trick has been my toolbox for a long time and whenever someone is having a hard time with multiplication or if I want to do a little light bit of you know teaching, I just show them this little trick and it lightens things up and go ahead and go more intense stuff. Now I was teaching a student a couple of weeks ago and his younger brother, his younger brother is in grade 5 and he's he's very inquisitive, very he wants to learn as fast as he can. It's incredible to feed information to, right? Same with the brother. They're very inquisitive inquisitive brothers and what he ended up doing, he kept on coming up to me and asking me to teach him mathematics, teach him mathematics and I usually don't start with a grade 5 because they're a little bit too young for me to teach because I like to teach at a fairly fast pace and I like to get into functions, get into applied mathematics if you want to call it that as fast as possible. So the only thing I could really teach him was really simple stuff and I basically taught him this multiplication table using your hands to multiply nice any one single digit number with well ten as well but any single digit number with nine. And he really liked it and he right away asked me, is there any other tricks? Is there any other tricks? I said that, you know, I told him I don't know any other tricks, right? And I all of a sudden right away I sort of said, you know what? Here's your homework. Find me another trick, find me another multiplication trick that you you know, you can find and next time I see you teach it to me and that's exactly what he ended up doing and he showed me a trick that I've never seen before and it's pretty complicated and he took me a couple of times when he was showing it to me to figure it out I was like, wow, that's really impressive and that's what I'm gonna teach you right now. Okay now You hold out your hands again It's the same thing you hold out your hands and what you do is instead of going one two three four five six seven eight nine and ten right you hold out your hands and you take your Thumbs and you call this six and the next one is seven eight nine ten, right? So this trick helps you multiply six all the way up to ten And what you do is let's say you want to multiply Six times eight, right? So either hand you take you pick the number six and on the other hand you go to the number eight, right? So six seven eight nine ten, right? So I'm gonna take six and connect it up with number eight, right? And if you're looking at a first-person perspective, it might make more sense to you, right? So six times eight and what you do now is every finger including the two that are touching before Where you're connecting and up to connecting you count that as tens, right? So this is ten twenty thirty forty, right? so That's forty you have right there. The rest of the numbers that are left the rest of your fingers that are left You multiply them together two times four is eight. So we got ten, twenty, thirty, forty Forty eight. That's what six times eight is. So let's try let's try another number or a couple other numbers anyway Let's take our number. So we've got six seven eight nine ten Let's go ten times ten. That's easy ten times ten you touch the two tens together This is ten, twenty, thirty, forty, fifty, sixty, seventy, eighty, ninety, one hundred, right? Ten times nine Ten, twenty, thirty, forty, fifty, sixty, seventy, eighty, ninety. Easy. Let's go eight times eight So you take both eights, right? Six seven eight you touch them together eight times eight is 10, 20, 30, 40, 50, 60 60 and there are two numbers left right two digits left you multiply them together two times two is four so 64 that's what eight times eight is and believe it or not and this balloon went through all the combinations just to make sure it works and it does work seven times nine let's go seven times nine six seven so I'm gonna take seven from this side six seven eight nine right so seven times nine this is ten if you're looking at first person ten twenty thirty forty fifty sixty right so that's sixty three there's three three and one left three times one is three seven times nine is sixty three let's go another two numbers right let's go seven times eight that's that's two numbers multiplied together I found that people have a hard time with remembering seven times eight so we're gonna go seven times eight so you connect them up so we got ten twenty thirty forty fifty three times two is six fifty six that's what seven times eight is right the weirdest combination for this hand multiplication is six times six now you take six and you take six and you connect them up right so six this is ten and this is ten so that's twenty and then you have four times four four times four sixteen so twenty plus sixteen thirty six and it works for six times six even so it's a brilliant little trick and it covers usually the numbers that people have the hardest times remembering what the what the numbers are from six to ten or from six to nine anyway okay and those are the only two hand tricks that I know of you know tricks that you can use to learn your multiplication table and at a certain point if you do enough of this you will learn your multiplication table and that's pretty important thing to know it's basically the basis of sort of where you have to start because multiplication is an extension of addition right so if you don't know how to multiply you're stuck with addition and subtraction right and from there that's basically us dealing the first basically to where you can call it four different operations we do with the real number set with numbers that we encounter okay and that's it those are the two little hand tricks that I know how to use multiplication and two two tools in my toolbox now okay and I thought I'd share it with you guys and but you might like I'll see you guys in the next video bye for now what you do is you start off with your thumbs as being six and you go seven eight nine ten right so if you want to for example multiply seven times eight so you take one hand and you go to seven you go six seven you take the other hand you go to eight you go six seven eight you touch the seven and eight together and then the way it works is all the numbers from the touching from your two fingers touching and back including the two fingers that are touching you count those as tens so this becomes 10 20 30 40 50 right the numbers after the two two fingers that you've touched what you end up doing is you multiply these two numbers together and there's two left on this finger and three left on this one so two times three is six so seven times eight is fifty one two three four five so that's 10 20 30 40 50 two times three six fifty six right and this works for all the numbers from six to ten multiplied together so what we're gonna do right now let's just go through and confirm that that's the case
