How to Subtract with borrowing

For people who are learning basic math skills, this video will show you how to subtract larger numbers which involve borrowing. If the top number on your rightmost digit is smaller than the number before it, you will need to borrow from the column before it. To do this, you will have to cross out the left hand number, subtracting one from its value. You can then add 10 to your original number and continue with your subtraction. If the left hand number is 0 and too small to be borrow from, you should move over another decimal place and borrow from the next number over. After this, you will have to borrow again, making your 10 into a 9 so that you will be able to bring 10 more over to your right hand column.
