Video transcript

what we're going to do in this video is add 48 thousand and twenty nine to two hundred thirty three thousand nine hundred thirty and like always pause this video and I really encourage you to try to figure it out on your own and let's see if we get the same answer and if we don't why all right so the way I'm gonna tackle this I assume that you've you had a go at it I'm gonna take the larger number I'm gonna write it on top I'm really doing the standard method there's multiple ways where you can add multiple multi digit numbers but what I'm going to do is really the most typical method and I'm gonna write the smaller number below it but I'm gonna match up the place value so I'm gonna write the ones place in the same column is the ones place on the top number so this is the ten thousands place so 48 thousand and twenty nine so nine is nine one zero ones 2 tens three tens so on and so forth and now I am ready to add so let's start in the ones place and if I'm adding numbers it's always a good idea to start in the ones place zero ones plus nine ones is nine ones and then I can go into the tens place three tens plus two tens is five tens this is going well alright then I go to the hundreds place nine hundreds plus the zero hundreds well that's just going to be nine hundreds so far so good alright now something interesting is gonna happen in the thousands place three thousands plus eight thousands well that would be eleven thousands but we can rewrite eleven thousands as one thousand and one ten thousand sometimes you might see this described as carrying the 1 3 plus 8 is 11 where you carry the 1 but all you're really doing is regrouping 3 plus 3,000 plus 8,000 is 11,000 we write the 1,000 here and then you write the 10,000 right over there in the 10,000 place and now so we have 1 10,000 plus 3 10,000 s plus 4 10,000 s so 1 plus 3 plus 4 that's 8 10 thousands or 80,000 and then last but not least we have these two hundred thousands right over there and we're done 280 1959 did you get the same answer
