Khan Academy

Supporting grades: 5

Description: Sal adds numbers, such as 3.53 + 4.72, by breaking them down into place values. Well the way that my brain tries to tackle it, is it says, alright, I have four and 22 hundredths, and 61 and 37 hundredths, how about I add the four plus the 61, so it's gonna be four plus 61, and then separately let me add the 22 hundredths to the 37 hundredths, so then I'm gonna add 22 hundredths plus 37 hundredths, and so four plus 61 is going to be equal to 65, and then 22 hundredths plus 37 hundredths, well, what's 22 plus 37? So let's say that we have three and 53 hundredths, and we wanna add that to four and 72 hundredths, like always, pause this video and see if you can figure it out on your own.
