Instructions and Help about When Form 2220 Multiply

Good I am welcome to the tape Math channel in this video today what we're gonna be have a look at is the fast way of multiplying two three-digit numbers together don't let's go so first of all we'll see we can multiply some numbers together I'll give you a question here which is 21 times 31 I'll give you 6 7 seconds to worth it go so time's up now have you got the answer is 651 you did really really well you got the right answer if you were busily reaching for the calculator but couldn't find it and time Oh bad luck you you should need a color code because I'm going to show you how you can work it out that quickly okay so don't don't get all despondent if you didn't work it out we'll go through that right now so I'll show you how to work these out so to get the first number of our answer we multiply the first digits in our two numbers here so two times three is six there you go got the first part of our answer we leave a blank space then to get the last number of our answer we multiply the last digits about two numbers here so one times one is one all right now to get this middle number here's a bit of a trick with this and to do this what we do is we multiply this number in this number this number and this number and we add the answer together so one times two is two one times three is three we had two and three together we get the answer 651 a pretty easy I will have a look at another one so what about 43 times 21 a little bit harder this time see how you go you're the answer yet okay I will start working through this one so again four times two is eight we leave the blank space one times three three then what we do is we go remember this on times four we heard that just 3 times 2 so 1 times 4 is 4 3 times 2 is 6 we had these together we get the answer of 10 then this leads to a bit of a problem here and it's a little bit of a trick that you probably want to get this spice here is only one spice it only has spice to fit one digit in okay so the digit that it actually puts in out of this 10 is this zero right here we put the zero there and this one here we carry across shall we add it on so the answer we end up getting is 1 plus 8 is 9 0 3 903 oh good I already we can go through one more okay so I'll rub that out let's have a look at one more question I think this time on you're doing a nicer this sort of perfectly sort of color and I'll do the question here 42 times 63 I'm going all out losing different colors today getting excited gopher I'm getting through so I can't even wait to get the answer here let's to start working there so get the first time at 4 times 6 is 24 leave our space 2 times 3 is 6 and then what we'll do and I hope I don't know because I have to remake this video because I stuffed up the answer this one I'll be honest on this one occasionally I I get on the side and I do actually make mistakes too but for YouTube videos we don't make mistakes we've always get it 100% correct like like you guys do okay but okay we multiply these two guys together 4 times 3 is 12 6 times 2 is 12 and so 12 plus 12 is 24 we're gonna add 24 on alright so there's a 4 there and through there all right what answer did we get we get the answer 2646 hey that's the right answer pretty cool right ok so if you practice these you get really really good and you get really really fast your teacher will be utterly standing to me a grade you up I don't know half you guys probably aren't even going to school but everybody I am today you know what people think you're a genius all right you want to push around too much people want stop talking to you and that's sort of new because I think it's very smart but I you do this you'll do really really well and yes you will make a few mistakes and we all make mistakes so what do they leave you with lastly gonna leave you with a couple of questions I'll write them up I'll get you to pause it work through them and then I'll work through the answers as quick as I can okay so here they are so 22 times 3432 so you go on that one what about 51 times 63 and what about 82 say times 51 so pause the video then I'll get back to you yeah got my seconds and we'll go through these all right so hopefully it works through those or through the answers of these right now okay so two times three is six and we leave that blank space two times two is four and then we add 4 and 6 together which is 10 so we're gonna get the answer of 704 okay there's our answer the next one 5 times 6 is 30 leave of space 1 times 3 is 3 and then we're gonna get that then then we're gonna put Nair is gonna be 3 times 5 which is 15 1 times 6 which is 6 15 plus 6 is 21 so I'll put that in a different color so it fits and it's gonna.
