[Music] hello everyone welcome to another lesson in this lesson we're going to see if does the order matter when we're adding so sometimes you'll see maybe a 3 plus 2 or 2 plus 3 and we want to see if what the answer be the same no matter how we arrange these numbers over here which are called Add Ins okay let's take a look at this example there are three birds on a tree branch to warbirds joined up now there are five Birds on the tree branch right remember there were three one two three two more birds join them one two now they're five one two three four five five Birds on the branch so that means three plus two is equal to five now let's switch these numbers around and see if two plus three is equal to five there are two birds on the tree branch three more birds join them here to two birds one two and here two three birds one two three how many birds on the branch one two three four five as you can see two plus three is equal to five so in this example we have three plus two is equal to five and over here we have two plus three is equal to five so that means although I switched the order we still got the same answer this look at some examples here's a 5 1 2 3 4 5 plus 1 because 1 is equal to 1 let's see 1 2 3 4 5 6 5 plus 1 is equal to 6 now let's flip around the 5 & 1 here's 1 1 here's a 5 1 2 3 4 5 and together three four five six so we see again that's the order does not matter five plus one is the same thing as one plus five they both equal to six so we have a two minute eight here's two one two and here's eight one two three four five six seven eight two plus eight is one two three four five six seven eight nine ten so two plus eight is 10 since we know order doesn't matter I can that's that's 8 plus 2 is going to equal to 10 here's 8 1 2 3 4 5 6 7 8 two one two and together one two three four five six seven eight nine ten 8 plus 2 is 10 so we can clearly see that the order does not matter when we're adding and that this whole goodbye Oh
