Description: smile and learn hello my friends I&#39;m back from Mars to show you some amazing tricks that will help you multiply numbers really fast ready to become Mental Math Stars today we&#39;ll learn how to quickly multiply by 10 100 and 1,000 with a few little tricks here we go how many astronauts are there on three space stations if 10 astronauts live in each [Music] one let&#39;s start by learning the trick to multiply any number by 10 as you can see we have to multiply three times 10 to find out how many astronauts there are in the space stations we can do traditional multiplication which takes longer or we can use our trick it&#39;s very simple we start by putting the number three and then adding a zero since 10 has only one zero easy right that means if we have three space stations with 10 astronauts living in each one there are 30 astronauts in total how many stars are there in three constellations if each one has 100 stars do you dare multiply by 100 imagine that in this universe there are three constellations and each one has 100 starss how do we know how many there are in total we can multiply the traditional way but we want to do it faster so first we write the number three and then we simply add two zeros from the number 100 there are 300 Stars how many aliens live on these five planets if each planet has 1,000 aliens on to the third trick how do we quickly multiply by 1,000 if 1,000 aliens live on each of these five planets we have to multiply 5 * 1,000 to find the total number of aliens [Music] as I said before we can do traditional multiplication but it would take us longer let&#39;s use our trick we write the number five first and then add the three zeros from the number 1,000 so if we have five planets and 1,000 aliens live on each planet there are 5,000 aliens in total now who wants to try it let&#39;s practice together what is 9 * 10 great 90 first we put the nine and add one zero because we are multiplying by 10 what what is 8 * 100 very good 800 first we put the eight and add two zeros because we&#39;re multiplying by 100 what is 2 * 1,000 exactly 2,000 we put the two first and add three zeros because we&#39;re multiplying by [Music] 1,000 great now you know how to multiply by 10 100 and 1,000 quickly and effortlessly use these tricks whenever you need to calculate something fast see you next time little math Stars [Music] we&#39;ve learned so much in just one video did you know there are many more videos imagine how much you could learn subscribe to the smile and learn educational channel to learn and have fun at the same time
Caption: Educational video for kids in which they will learn how to multiply mentally by 10, 100 and 1000 in a quick and easy way.

When we need to multiply a number by 10, 100 or 1000, instead of using traditional multiplication, which can take more time, we can use a very simple trick. We just need to add zeros to the original number:

To multiply by 10, we add one zero to the end of the number, since 10 has only one zero. For example, if we multiply 3 by 10, we simply add a zero to 3 and get 30.
To multiply by 100, we add two zeros.
To multiply by 1000, we add three zeros.

This video is a very useful and interesting resource for children. This trick makes mental math easier and helps to get the result faster. It is an excellent video for primary education.
