Use column subtraction to calculate the following: 7,594 take away 482.

When we use column subtraction, we subtract in columns. We start by subtracting the ones, then the tens, the hundreds, and then the thousands. Let’s subtract. What is four ones subtract two ones? Well, we know that four take away two is two, so we can write the answer in the ones column. Now we can subtract the tens. We’ve got nine 10s, and we need to take away eight 10s. Nine take away eight is one. So we’ve got one 10 left.

In the hundreds column, we’ve got five 100s and we need to take away four. Five take away four is one. So we’ve got one 100 left. And in the thousands place, we’ve got seven 1,000s and nothing to subtract, so we can just write the seven in the thousands place. 7,594 take away 482 is 7,112. We used column subtraction to calculate the answer.
