  • It's easier to just start borrowing from the number to the left of the last number that needs to borrow and keep carrying 10 down to the right.

  • It's better to cross out and subtract BEFORE you borrow. i.e cross out the 30 and make it 29 before you bring the one over.

  • I'm about to take the GMATs to get into graduate school and they don't allow calculators. Even after 4 years in college as an accounting major I needed this refresher!

  • i hear you man

  • The method of borrowing you show in this video is much more efficient than the method I learned at school. Thank you!

  • You are just plain awesome with all of your videos- nothing else can be said-Thanks a ton!

  • khan.....

  • hey can anyone show me how you subtract a larger decimal from a smaller decimal. example 6.0-7.1 WITHOUT making it 7.1-6.0 and just placing a minus sign in front.....i want to see how it becomes -1.1, like first in 6.0-7.1 you would borrow 1 from 6 since 0 is less than 1. then 6 would become 5 right? or something...

  • @powerhouse

    If you don't want to change it around, then you should make it 6.0 + -7.1

    6 + -7 = -1

    0 + 1 = 1

    so your answer will be -1.1

    sorry I had to demonstrate it this way. I can't align and for it to show in this comment box.

  • ahhhhhh this is bulshit i hate how people only do easy math examples i need problems with more numbers you have to browo from

  • THANK YOU SO MUCH!! i neede help with this so bad.

    .

  • you have no idea how important this website is to me.. im 25 and i made many many wrong decisions in my life and one of the biggest was not graduating highschool now that i am a mother and have finally realized how important ed is, i tried going to ged classes and that discouraged me bc i cnt learn at everyone else's pace in class and im embarrassed to ask too many q's if i dnt get.. needless to say U SAVED MY LIFE!!!!!! thank u from my son, my mother and I. bless u

  • thank u so much i had big problem with decimals now i understood and i will not have more broblem . thanks

  • how could someone borrow 1 from zero?

  • Assuming you are referring to his comment at 2:25 - all he means is that you can either treat the numbers 3 and 0 as thirty and borrow 1 from thirty making it twenty-nine OR you can borrow from 3 to make it 2, then *borrow from 0* (which is now a 10 due to borrowing from the 3), to make it 9. Either way you get 29. At least that's what I think he meant.

  • I'm going after my GED. You are so awesome. I learned more from you in a half an hour than 12 years of math in school!

    Thanks.

  • @eknow360 Same here, congrats on GED decision.

  • I have a learning disability and out of all the math teachers I had I never understood till know, that was great I understand subtracting decimals Thank you.

  • My son had a 'ah-ha' moment after watching your video. Thank you!!

  • the hell with college, i'll just learn from this dude, i suck at math and in college i had to take remedial math ahahha lost cause. But no college is good

  • I'll (hopefully) be starting dual credit college classes soon, and I know if I just "listen" to the teachers, come home and re-learn but the pwn-ness of Sal-sama, I'll be fine. xD
