Hi, I'm Rob. Welcome to Math Antics. In our previous lesson, we learned how to add mixed numbers. In this lesson, we're going to learn how to subtract them. Subtraction is always a little trickier than addition because subtraction does not have the commutative property. That means that the order of the numbers you're subtracting matters and you can't switch it like you can with addition. Subtraction is also tricky because if you try subtracting a number from a smaller number, like 1 minus 5, you get a negative answer. Fortunately, we're not going to cover any problems with negative answers in this video. But as you'll see in a few minutes, there are cases where it seems like you need to subtract a bigger number from a smaller one. At first, all of this means that subtracting mixed numbers can be quite a bit more complicated than adding them. But don't worry, we'll take it one step at a time. And it'll help a lot if you make sure that you have a good understanding of topics like adding mixed numbers, subtracting fractions, order of operations, and multi-digit subtraction. Because this lesson builds on all of those concepts. Okay, to see why subtracting mixed numbers is trickier than adding them, let's have a look at two problems side by side: 5 plus two and one-third, and 5 minus two and one-third. We learned how to do problems like the first one in the previous video about adding mixed numbers. Since two and one-third just means two plus one-third, we learned that we could rewrite the problem like this and simply add up the whole number parts to get the whole number part of the answer. Five plus two is seven, so the answer is seven and one-third. But if we try...
