Hi, everyone. So today we're asked to add 832 and 199. So the easiest way to do this is when you have numbers with two or more digits is to line them up vertically and then add straight down. So you always want to make sure that your ones places they're lined up because that'll line up the rest of the number. But in cases where you have numbers with the same amount of digits in this case, these two bold hectoring you can just lend it up like I have here. So we start in the ones place with addicts. We have two plus nine equals 11. Okay, so we need to take the digit and the right most place, put it in the place we're working in and then carry the other digit over. So now we have completed the ones place we're moving on to tense. We have three plus nine equals 12 plus the extra one we have, which gives us 13 again. We need to put the right digit down in the place, were working and carry the extra one. So now we have a plus one, which gives us mine, plus the extra one, which gives us 10 again. We need to put the right digit down here, but in this case, we don't have anything to add in the thousands place. So we can just put this extra one right in front of it right here. So 832 plus 199 equals 1031.

And hi everyone. So today we're going to add 775 and 369. So whenever you have a number that has two or more digits, it's always best to line them up vertically and then I'm straight down. So you always want to make sure you're ones places re lined up. If you have a number, that is different digits. So in this case, these both have three, so they line up perfectly. So we started the ones place we have five plus nine equals 14. So what we need to do is put the four in the place were working in and carry the one. Okay, so now we have seven plus six equals 13 plus the extra one equals 14 again. We need to put the four and the place were working in and carry the extra one. So now we have seven plus three equals 10 plus the extra one equals 11. Now, in this case, we put the one here, and we can just put this one in the place next to it. So 775 plus 369 equals 1140

We're in decimal operation and they were adding 16.92 and 7.6. Let's go ahead and rewrite that. We have 16 boy 92 in 7.26 So when we're I'm setting up our addition of decimals, it's very important to have our dozen more points over here lined up. Yeah, let's go ahead and add. We thought two plus six is a nine plus five minutes 14 and we carry over one. Let's bring down our our decimal point over here and now we have one plus six plus seven, which gives us 14 carry over that one from 14. And of course, one plus one is two, and that's her answer. 24.48.

Hi. Okay, so today we're adding 18.37 9.36 so let's go ahead and set them up. Over here you have 18.37 9.36. Again, it's very important to have those two decimal points line up and let's go ahead and you got seven plus six over here, which goes is 13 carry over, one for 13. Then we got three plus three, but one that will secure it over. So you have seven. We bring down our decimal point eight plus nine is 17 and then one from 17. Get security over one plus one, Of course is to So there's our answer 27.73.
