Lesson Transcript
Instructor: Yuanxin (Amy) Yang Alcocer

Amy has a master's degree in secondary education and has taught math at a public charter high school.

Addition is one of the basic operations of math. You can say that the whole of mathematics is based on addition. Without addition, we wouldn't have higher math. Watch this video to learn how to add.

What is addition? We can say that addition is the combining of two or more small groups of items together to make one big group. When we add, we usually start out with two or more numbers and then we combine them into one big number. We will see how this is done in this video lesson, so keep watching. I'm also going to show you a way of thinking about addition that might make it easier for you.

What did we just do? We just added without thinking about it too much. So, to add, we are simply combining two or more amounts and finding the total.

In math, we have a symbol for addition. It is the symbol that looks like a cross: +. We place this symbol between two numbers that we want to add together. We can just add two numbers together, such as 1 + 1, or we can add a string of numbers together, such as 1 + 2 + 3. We can keep on stringing numbers together to add them all up. Now let's see how to add two numbers together.

Let's say we want to add 2 and 3 together. How do we go about doing this? We can think of the 2 and 3 in terms of money. If we were shopping and we wanted to buy one candy bar that was two dollars and a second candy bar that costs three dollars, how much money would we need to buy them both? We would need five dollars since 2 + 3 = 5. We have just added.

Another way to visualize our addition is to think of the 2 and 3 in terms of number of items. We can picture first two donuts and then three donuts. We then picture all the donuts together and ask ourselves 'How many donuts do we have total?' We will see that we have a total of 5 donuts. So 2 + 3 = 5.
