Subtraction - Subtracting Whole Numbers - YourTeacher.com

For a complete lesson on subtraction, go to http://www.yourteacher.com - 1000+ online math lessons featuring a personal math teacher inside every lesson! In this lesson, students learn to subtract numbers with two or more digits, such as 985 - 47. The first step is to line up the numbers vertically so that the units digits are in the same column. Next, subtract the units digits, the tens digits, and the hundreds digits. When subtracting the units digits, notice that it is not possible to subtract 7 ones from 5 ones, so 1 ten must be borrowed from the tens column, leaving 7 tens and 15 ones. Now, subtracting the units digits, 15 - 7 = 8, subtracting the tens digits, 7 - 4 = 3, and subtracting the hundreds digits, 9 - 0 = 9. So 985 - 47 = 938. Note that the answer to a subtraction problem is called the difference, so the difference of 985 - 47 is 938.

@Vergothe Maybe because in the real World you wouldn't be able to say "Sorry, that's too difficult for me, can I just change some of the numbers so it's seaier?".

I'm a 80s child so pre PCs, laptops, mobile phones etc What amazes me is how few teens downwards can't do mah in their head.
