In math subtracting one number from another, arrange the numbers according to the place values and carry out the operation column by column from right to left.
When two or more numbers are to be subtracted successively, it must be carried out in steps subtracting two numbers at a time and do the regrouping when necessary.

4. Rewrite the number sentence in a place value chart as follows:
|
|
|
