 Hello and welcome to another session on speed math Guys last time we were doing multiplication of two numbers near thousand and those two numbers were less than thousand now We are going to see the case to where the number of both the numbers are greater than thousand Okay, so a into B. We are performing and a is greater than thousand and B is greater than thousand now in this case when I say greater than thousand I'm not talking about numbers like one five seven six or one two three nine on all that no They have to be near thousand close to thousand now that nearness is very subjective term that depends on How fluent you are with multiplication? So we will be restricting it to let's say, you know one zero zero or Thousand two one zero two zero. Let's say maximum like this So then it becomes easier for us to do the or perform the multiplication. So let's take examples and understand Likewise, we did it for the case of thousand here. Also, we will be or for the case of hundred. Sorry, we will be doing the same thing here now, how far is this from Thousand so plus four and this one plus five, but only thing we have to remember in these cases. We have to allocate three places for hundreds tens and Units place of the product now how to get those so multiply four times five is 20 So simply write 20 and since there is nothing so you'll write zero Okay, so that's done rest is as we have been doing so far 104 plus five that is one zero zero nine. So the product of this to Do three digit numbers to three digit number is one zero zero nine zero two zero Let's go ahead and take another example. This was example number one. Let's take example number two Let's say we are multiplying one zero zero one with one zero zero seven again How away from thousand plus one how away from thousand? Plus seven since it is more than thousand we are taking positives You had seen in the previous session when it was less than thousand we were taking negatives, right now multiply again So what will you get one time seven is seven material? You will be writing zero zero seven the bond zero zero seven isn't it so zero zero seven correct? This is done and then simply this or this so it is one zero zero eight So one zero zero seven plus one is one zero zero eight and you simply write like this. So this is the product Yeah Third one. Let's take another example. So as many you you know questions you will tackle you will become more and more fluent one zero zero nine and One zero one six now. These are little bigger numbers as compared to the previous ones. So now Knowledge of tables will be a little handy. So nine and sixteen are away, you know They are away nine times or from by nine from thousand and sixteen from thousand again So multiply sixteen times nine again one four four all three digit numbers are there So no not to worry and now simply add this. So this is one zero two five and this is the product So you are doing multiplication so fast Okay, another one. Let's take another one. So let's say you have to do one zero one two and One zero one five right now numbers are a little bigger. So again plus twelve plus fifteen But still manageable. So twelve times fifteen is one eight zero So right one eight zero and One zero two seven done Right, so one zero five one zero one five plus twelve is one zero two seven which i'm writing here So this whole is the product Okay, I think this is you know making sense to you and one last one will take so a little bigger One zero one nine One zero one one Okay, I have to do this. So this is plus nineteen and this is plus eleven. So if you multiply Nineteen times eleven is nothing but two zero nine And if you do this some so you'll get one zero three zero So the product is one zero three zero two zero nine So you are able to handle Such big numbers and you are able to multiply very quickly So you can practice a few more from our practice session and you'll get to see That these calculations are becoming so easier for you. Okay in the next session Let's take the case where one number is lesser than thousand one number is more than thousand
