Subtracting with regrouping (borrowing) | Early Math | Khan Academy

Learn how to subtract 23 from 65 by thinking about tens and ones.

Early Math on Khan Academy: Math begins with counting. It's the most important skill we learn in our early years and becomes the foundation for all other math concepts. Once we can count, we can add, subtract, and measure the world around us. Shortly thereafter, we can learn about place values, plots, graphs, time, money, and shapes. These early math skills are presented in this subject's tutorials in a straightforward, understandable, and (dare we say it) fun way!

About Khan Academy: Khan Academy offers practice exercises, instructional videos, and a personalized learning dashboard that empower learners to study at their own pace in and outside of the classroom. We tackle math, science, computer programming, history, art history, economics, and more. Our math missions guide learners from kindergarten to calculus using state-of-the-art, adaptive technology that identifies strengths and learning gaps. We've also partnered with institutions like NASA, The Museum of Modern Art, The California Academy of Sciences, and MIT to offer specialized content.

For free. For everyone. Forever. #YouCanLearnAnything

I was 6 years old I didn't pass the test and then I watched this video and it helped me learn thanks for the video cause it help me learn!!!

The ways I'd do 83 - 25 is:
3 - 5 = -2
80 - 20 = 60
60 - 2 = 58

For some reason I find that easier, even though in school I was taught the way that you show in the video.


And another way you could also do it is:

83 - 20 = 63
5 - 63 = 58

which I also find way simpler and faster than the "normal" way shown in the video.

I always borrowed in math a different way. But for whatever reason, if I try that method when subtracting numbers with decimals, it doesn't seem to work. So I forgot all about this "old fashion way". This video sure did help. Thank you. 😂

Khan academy is the best. This will help my son be in Nintendo hopefully

Regrouping helped me with my math, thank you!

(Subtracting 25 from 83: We cannot subtract 3 from 5 so we will take from 8 which means the ten's place so 8 can give only 1 so 8 became 7 and 3 became 13 so we need to keep 1 at the top of 3 so 13 minus 5 is 8 and 7 minus 2 is 8 so 83 minus 25 is 58.)

Thank you so much for taking the time to share these videos!

All thanks to this I’m getting screamed by my parents and making me give up on School

[thehriscareerworld]

change 83 by + 2 to 85
85 - 25 = 60
Now reverse the 2 
60 - 2 = 58
So much for common core :-)

Thank you so much im smart in math but I struggle in regrouping/borrowing but this is so simple now i can ace my test

[donovanburney]

and I'm even eight years old I should be in school right now and I'm going to be in school next year so thanks for teaching me this

[lacyoliviaa]

I am in online school and they didn’t explain well, and this video helped me thank you❤

[Terkzorr]

I'm 26 and this actually helped me. I totally forgot to do subtraction, division and multiplication on paper (I only remember the addition method from school). Damn calculators. :)

[highlightsrecap]

I am watching this video to teach my little sister

[makenamurphy]

This video is even more perfect than I even expected

[Moon_Dibiase]

I was for some reason never tought this so thanks for helping

[ummeaiman]

Thank you for sharing this information

[Crick]

I really hope you're going to go into creative uses of mental math. Maybe use the Japanese Multiplying by Parts. That's the only trick I know.

[rgomez]

Thank you so much!! I’m homeschool so this helped my study!
