the past week we've been working on multiplying with decimals and using one digit decimals * 1 days decimal value of 10 lb of 10 and we use graph paper or a 100 block that look very similar to this okay and now what I'm going to do is I'm going to expend what you are doing here without using the picture models to illustrate how to multiply with decimals what we call Al using standard algorithm just calculating in the traditional fashion Okay so Venom X with decimals multiply with decimals okay and there is a few rules that I wanted to follow and if you follow this it should be fairly easy for YouTube calculate on your own all right I'm going to go back to when we started the school year we were talking about multiplying with whole milk all right and we had two digit with a two digit you remember that again goes to the same process and we talked about the LV the Louis Vuitton we follow the path and in the sweat drop and I talked about the dancing boys and girls dancing number one I say if you follow these rules we will be in pretty good shape for my rules to the side over here so that way I can show my work here so you're my simple rules number one Mundelein all digits behind the basketball number two document and I'll show you exactly what I mean document d basketball coins and be underlined number 94 stat before X the digit using can I call the LV method is the Louis Vuitton then number 4 with your product which is your answer to your multiplication with your product place decimal point and underlined in Iowa model HEB or you don't even need to put this down a little bit are that's okay we are going to in your original problem or right what you just did appear with the decimal point how many on the line 9 number three where we already know that we're going to just multiply using our LG model we know how to do that then number for is the only thing that's really different is with your final answer of your that you got from step 3 I'm just going to go back and underline and put my decimal point in my final answer and we're done okay so here we go I think you are going to surprise yourself how easy this really is all right so I'm going to follow this but I am going to now take my trusty marker and let's say I have to go to basketball 4 * 3 decimal 5 and I try to use different digits not the same one when I remodel for you so you know exactly did you I'm speaking up here's my original problem and my first rule was to go on the line that digits behind the decimal so what am I going to underline in this problem yes Miss Johnson and I'm going to underline the five I just missed that one for you was that hard I didn't think so Mac says number to document the decimal point decimal point there is and how many am I going to underline now so now I just go wine on the line to underline I'm done with the now I just use that 300 Steph Curry is as X that they just using the LV so I'm going to use credit cards 5 L go up and across and then I will use the color black in this one that's well now I'm going to put starting from 3 show my V all the way to the for all the girls wanna ride and move back so there's my L shape in the V shape right whoever my greeter is just be aware okay the largest number did you ever have the most by in your lifetime what is 1 digit times a one digit that is it so I'm going to follow that method since I have my red I'm going to go with my red car 5 times what 4 is what I took care of it over here time for 20 is my zero and then regroup tattoo with my heart there are my kisses man 5 * 2 prostitute so I just write 12 crosses went out and what do I do with the five crocodile and put a Circle so now without Circle I just bring that Circle downstairs there it is you see how I just crossed out just like I did with the Rays baseball right now using my black pants I'm going to do the same thing with my three and again it is on the same line of my sweat dropped my zero that I I have 33 * what 12 up there it is man ray one there's my heart oh my God hey I'm scared of her next I do with free time. My heart watch how simple this is as ready as the two products together and I get zero year or year with your product product 840 place the decimal point and unlocked so I take this that I wrote and now I am gone thank you how many am I going to underline where do I start from right one on the line and therefore my decimal point must go where is my final answer to my problem what is it if you use this method it will never fail you it will never fail you that's how simple multiplying with decimals yeah let's look at my rule again underlined all the digits in decimal and that's what I did the five test document just put to the side so I have a smoke and how many business are behind the decimal to a man as George Foreman worth a plugged it in and forget about it yeah it's all that's right I forgot about it and all they did is I went back to this original and just use the Louis Vuitton and showed my patch each am I multipliers and then I follow and 1 digit times one digit and make sure you add in what you recruit Nando's drop after they are finished with a x 0 don't bring down the five please this is zero that's what I did man all your next multiplying products must go on the same line as my sweat. Then add it all up we got 840 then because we have decimals and we documented it we come back to my product that we had and we on the line starting from the far right at 12 and lines of 12 and the decimal point is in front of that which is between 8 and 4 and so therefore my final answer is a + 4 10 or 8 and 40 hundred and that is it folks stop this at once and I'm going to stop
