Example Question #1 :Subtracting Multi Digit Numbers
Solve:
When we subtract multi-digit numbers, we start with the digits in the ones place and move to the left.
Let's look at the numbers in the ones place:
Next, let's look at the numbers in the tens place:
When the top number is smaller than the bottom number, we have to borrow from the number to the left because we can't takeaway fromsinceis the smaller number. In this case, we are going to look to the. We only ever need to takeaway from the number to the left. For this problem, that will leave us with ato replace the. So far, your work should look something like this:
Remember, we've borrowedfrom the hundreds place, so we can put ain front of the number in the tens place. So far, your work should look something like this:
Now, we can subtract the numbers in the tens place:
Next, we can subtract the numbers in the hundreds place:
Your final answer should be
