Title: Learn to subtract 2-digit numbers from 3-digit numbers with regrouping.

You can already subtract tens from a 3-digit number with hundreds, tens, and ones. In this lesson, you'll learn to subtract any two-digit number from some 3-digit numbers, like this.
142 minus 77.
We start subtracting in the ones place.
We can't subtract 7 from 2, so we have to take a ten to make ten ones.
We cross out the 4 to show that we took a ten.
We put 3 here to show there are 3 tens left and we put a 1 here to show we have 10 ones.
Now we have 12 minus 7, which is 5.
Now the tens place.
We have 3 minus 7. We can't subtract 7 from 3, so we have to take a hundred to make ten tens.
We cross out the 1 to show we took a hundred.
We don't need to put anything here, because there are no hundreds left.
We put a 1 here to show that we made ten tens.
Now we have 13 tens minus 7 tens, which is 6 tens.
Now the hundreds place.
We have no hundreds left, since we crossed out the one hundred and no number here.
That means we're done.
The answer is 65.
Another example. 137 minus 68.
We start subtracting in the ones place.
We can't subtract 8 from 7, so we have to take a ten to make ten ones.
We cross out the 3 and put 2 here to show there are 2 tens left.
We put a 1 here to show we have 10 ones.
Now we have 17 minus 8 which is 9.
Now the tens place.
We have 2 minus 6, so we have to take a hundred to make ten tens.
We cross out the 1, but we don't put anything here because there are no hundreds left.
We put a 1 here to show that we made ten tens.
Now we have 12 tens minus 6 tens, which is 6 tens.
Now the hundreds place.
We have no hundreds left, since we crossed out the one hundred and no number here.
That means we're done.
The answer is 69.
Another example. 113 minus 45.
We start subtracting in the ones place.
We can't subtract 5 from 3, so we have to take a ten to make ten ones.
We cross out the 1 and put 0 here to show there are no tens left.
We put a 1 here to show we have 10 ones.
Now we have 13 minus 5, which is 8.
Now the tens place.
We have 0 minus 4, so we have to take a hundred to make ten tens.
We cross out the 1, but we don't put anything here because we have no hundreds left.
We put a 1 here to show that we made ten tens.
Now we have 10 tens minus 4 tens, which is 6 tens.
Now the hundreds place.
We have no hundreds left, since we crossed out the one hundred and no number here.
That means we're done.
The answer is 68.
In the rest of this lesson, you'll solve problems like these.

Title: Learn to subtract 1-digit numbers from multiples of ten with regrouping.

You can already subtract a one-digit number from 10 and 20.
In this lesson, you'll learn how to subtract a 1-digit number from other numbers made up of tens.
Here's an example. 40 minus 2.
Forty is 4 tens.
We start subtracting in the ones place.
We can't subtract 2 from 0, so we have to take a ten from 40 to make ten ones.
We cross out the 4 in 40 to show we took a ten and we enter a 3 here to show we have 3 tens left in the tens place, which is 30.
We put a 1 here to show that we made ten ones.
Now we subtract 2 from the 10 ones.
10 minus 2 is 8.
In the tens place, there's nothing to subtract, so we bring down the 3.
That gives us 38.
So 40 minus 2 is 38.
Another example. 60 minus 7.
Sixty is 6 tens.
We start subtracting in the ones place.
We can't subtract 7 from 0, so we have to take a ten from 60 to make ten ones.
We cross out the 6 in 60 to show we took a ten and write a 5 above it to show there are 5 tens left, which is 50.
We show that we made ten ones by putting a 1 here.
Now we subtract 7 from the 10 ones.
10 minus 7 is 3.
There's nothing to subtract in the tens place, so we bring down the 5 we have left.
That gives us 53.
So 60 minus 7 is 53.
Last example. 80 minus 4.
We start with the ones place.
We can't subtract 4 from 0, so we have to take a ten from 80 to make ten ones.
We cross out the 8 in 80 to show that we took a ten.
And we write 7 here to show there are 7 tens left, which is 70.
We put a 1 here to show that we made ten ones.
Now we subtract 4 from 10.
10 minus 4 is 6.
There's nothing to subtract in the tens place, so we bring down the 7 we have left.
That gives us 76.
So 80 minus 4 is 76.
In the rest of this lesson, you'll work problems like these. You can use these boxes if you want, but you don’t have to.

Title: Learn to subtract 1-digit numbers from 2-digit numbers Pt. 2.

You already know how to subtract when you have to take a ten.
In this lesson, you'll learn how to use that to subtract with numbers that have both tens and ones.
Here's an example. 43 minus 7.
We start with the ones place.
We can't subtract 7 from 3, so we have to take a ten from 40 to make ten ones.
We cross out the 4 in 40 and we enter a 3 here to show we have 3 tens left.
Now we put a 1 here to show that we have 13 ones.
So now we have 13 minus 7.
13 minus 7 is 6, so we put a 6 in the ones place of the answer.
There's nothing to subtract in the tens place, so we bring down the 3 for the 3 tens we have left.
That gives us 36.
So 43 minus 7 is 36.
Another example. 65 minus 8.
We start with the ones place.
We can't subtract 8 from 5, so we have to take a ten from 60 to make ten ones.
We cross out the 6 in 60 and we enter a 5 here to show that we have 5 tens left.
And we enter a 1 here to show we have 15 ones.
Now we subtract 8 from 15.
15 minus 8 is 7.
There's nothing to subtract in the tens place, so we bring down the 5 for the 5 tens we have left.
That gives us 57.
So 65 minus 8 is 57.
Last example. 37 minus 8.
We can't subtract 8 from 7, so we have to take a ten from 30 to make 10 ones.
We cross out the 3 in 30 and we enter a 2 here to show that we have 2 tens left.
And we enter a 1 here to show we have 17 ones.
Now we subtract 8 from 17.
17 minus 8 is 9.
There's nothing to subtract in the tens place, so we bring down the 2 for the 2 tens we have left.
That gives us 29.
So 37 minus 8 is 29.
In the rest of this lesson, you'll work problems like these. You can use these boxes if you want, but you don’t have to.
