00:00Hello kids. I am sorry that I'm not livelier today. I am sick and I have a really bad cold.
00:09I really want to feel better and I know just the thing to help me. Will you guys help me
00:14feel better? Great! Let's look over here. To help a number feel better, and I am the
00:23number one, you have to work on some math problems. Today I want to work on subtraction
00:29with regrouping. Here we have a worksheet, and if you can help me work on two problems,
00:35I know that I will start feeling better. Here we have the problem 25 subtract 16. When subtracting,
00:44we start with the ones place first. In the ones place, we have 5 subtract 6. Can we subtract
00:51this or do we need to regroup? You are correct. We need to regroup. To regroup, we need to
01:00take one of these tens and trade it in for 10 ones. In the tens place, we have a 2, which
01:06stands for 20. If we take away one of these tens, we first need to cross out the 2 and
01:12put a 1 there. Next, we need to cross out the ones place because we no longer have 5
01:18ones, but 15 since we added 10 ones to it. We can now start subtracting. In the ones
01:26place, we have 15 subtract 6, which equals what? 15 subtract 6 is 9. Great job! Now we
01:36subtract the tens. What do we get when we subtract the tens column? Zero. So we do not
01:45need to put anything down. So what is our answer to 25 subtract 16? The answer is 9!
01:53You guys are awesome! Wow, I am starting to feel a little better already. Thanks! Here
02:00we have one last problem. Go ahead and pause the video and work on it on your own, and
02:05then we will go over it together once you are done. Alright, if you are ready to go,
02:13let's get started. We will move kind of quick, so pay attention. We start in the ones
02:19place and we have 0 subtract 7, which we cannot do, so we need to regroup. We take one of
02:25the tens from the tens column and put it in the ones column. We cross out the 8 and put
02:33a 7 there to show how many are left. Now we cross out the 0 in the ones column and put
02:39the 10 we borrowed. We are ready to subtract. What is 10 subtract 7? The answer is 3. Now
02:48on to the tens column. We have 7 subtract 2, which gives us 5. The answer is 53. 80
02:57subtract 27 is 53. Great job! Awesome job guys, you did great and I am feeling a lot
03:06better. If you have questions, do not be afraid to ask. See you later, goodbye.
