Addition - Adding Whole Numbers - YourTeacher.com

For a complete lesson on addition, go to http://www.yourteacher.com - 1000+ online math lessons featuring a personal math teacher inside every lesson! In this lesson, students learn to add numbers with two or more digits, such as 139 + 25. The first step is to line up the numbers vertically so that the units digits are in the same column. Next, add the units digits, the tens digits, and the hundreds digits. Adding the units digits, 9 + 5 = 14, which is the same as 1 ten and 4 ones, so put a 4 in the units column and carry a 1 to the tens column. Now, adding the tens digits, 1 + 3 + 2 = 6, and adding the hundreds digits, 1 + 0 = 1. So 139 + 25 = 164. Note that the answer to an addition problem is called the sum, so the sum of 139 + 25 is 164.

@xboxlambo640 calm your fat tits. who said YOU were socially awkward or asian, i think this is a good video for anyone who would want another teacher to watch if they only had one cuz theyre homeschooled. kids who are homeschooled are probably smarter than kids that go to public school like stfu bitch i wasnt saying shit to you. holy damn & its also a good refresher vid for ANYONE or just kids who learn at home. like stfu
