Subtraction With Regrouping Lesson

If you are looking for a good example to teach your kids math subtraction with regrouping that really works – and I will prove it to you in a moment – then please read this message very carefully. It will be the most important information for subtraction with regrouping lesson you read all year.   As you know each digit of a number in our number system has a different place value (ones, tens, hundreds, thousands, etc) Always subtract within the same place value column when subtracting numbers.    Example:                                  6 8 2 3 - 4 7 6 9

Step 1 Write the problem in the columns.       Step 2 First, subtract the ones      Subtract the bottom ones place digit from the top ones place digit (3-9).   Here, we need to regrouping the number to make the top value larger. Regroup 1 tens into 10 ones, so that the 3 becomes 13. 13 ones – 9 ones = 4 ones. The 4 is placed below the line in the ones place column.   Next, subtract the tens.       The top tens place value becomes 1 after subtraction with regrouping one tens from it.   Regroup 1 hundreds into 10 tens. 10 tens + 1 tens = 11 tens, 11 tens – 6 tens = 5 tens. Then, subtract the hundreds      The top hundreds place value becomes 7 after subtraction with regrouping one tens from it.   7 hundreds – 7 hundreds = 0 hundreds   Finally, subtract the thousands.     6 thousands – 4 thousands = 2 thousands.   In this lesson, we use subtraction with regrouping method to solve the problem that is 6823 – 4769 = 2054
