Complete the following table.

In this question, we’re given a four-digit number, 5,666. In this column, we have to write the answer to 5,666 take away one. In the next column, we have to subtract 10 from 5,666 and write the answer here. Next, we need to subtract 100 from our number and write the answer here. And in the last column, we need to subtract 1,000 from our number and write the answer here.

Writing the number in a place value table helps us to understand the value of each digit. The number 5,666 has five 1,000s, six 100s, six 10s, and six ones. What is 5,666 take away one? We already know our number has six ones. If we take one away, we’ll have five ones left. 5,666 take away one is 5,665. The ones digit has decreased by one.

Now we need to take away 10 from our number. The tens digit is also a six, and this is worth 60. If we take away one 10, we’ll have five 10s. The tens digit has decreased by one.

Now we have to take away 100 from our number. The digit in the hundreds place is also a six. If we have six 100s and we take one away, we have five 100s left. 5,666 take away 100 is 5,566. The hundreds digit has decreased by one.

Finally, we need to subtract 1,000 from our number. The digit in the thousands place is a five. And if we take one 1,000 away, we’ll have four 1,000s left. 5,666 take away 1,000 is 4,666. This time, the thousands digit decreased by one.

We completed the table by taking away one, 10, 100, and 1,000 from the number 5,666. The missing numbers are 5,665, 5,656, 5,566, and 4,666. We used our knowledge of place value to help us subtract.
