How do you borrow when subtracting decimals?
Summary: When subtracting decimals, first line up all the decimal points in a column. When needed, write one or more extra zeros to the right so that both decimals have the same number of decimal digits. Subtract digits in the same place-value position. When needed, borrow a group of ten from the column to the left.
How do you explain long subtraction?
Long subtraction lets you find the difference between two numbers. Align your numbers so that the place values line up in columns (ones, tens, hundreds, etc.) If the bottom number is larger than the top number you need to regroup, borrowing value from the number in the column to the left.
How do you add and subtract decimals step by step?

What is the rule for borrowing in subtraction?
In subtraction, you borrow when you are subtracting one number that is greater than another (the subtrahend is greater than the minuend). 35 – 2 would not need borrowing/regrouping. 32 – 5 would use borrowing/regrouping because you can’t subtract 5 from 2 in this example.
