Mastering Double Digit Addition with Regrouping

Double digit addition with regrouping can seem daunting at first, but with the right approach, it can become a breeze. In this article, we’ll break down the steps and provide examples to help you master this essential math skill.

Understanding Regrouping

Regrouping is a crucial concept in double digit addition. It involves carrying over a digit from one place value to the next when the sum of two digits exceeds 9. This process helps ensure that the calculation is accurate and efficient.

Step-by-Step Guide to Double Digit Addition with Regrouping

  1. Start with the ones place: Begin by adding the digits in the ones place (the rightmost column). If the sum is less than or equal to 9, write the result in the ones place.
  2. Regroup if necessary: If the sum of the digits in the ones place exceeds 9, regroup the excess digit by carrying it over to the tens place.
  3. Add the tens place: Add the digits in the tens place, including any regrouped digits from the ones place. If the sum exceeds 9, regroup again.
  4. Write the final answer: Combine the results from the ones and tens places to form the final answer.

💡 Note: When regrouping, always carry the excess digit to the next place value, rather than writing it in the current place.

Example Problems

Problem 1: 45 + 27

  1. Start with the ones place: 5 + 7 = 12 (regroup the 1)
  2. Add the tens place: 4 + 2 + 1 (regrouped) = 7
  3. Write the final answer: 72

Problem 2: 93 + 48

  1. Start with the ones place: 3 + 8 = 11 (regroup the 1)
  2. Add the tens place: 9 + 4 + 1 (regrouped) = 14 (regroup the 1)
  3. Add the hundreds place: 1 (regrouped) = 1
  4. Write the final answer: 141

Problem 3: 75 + 39

  1. Start with the ones place: 5 + 9 = 14 (regroup the 1)
  2. Add the tens place: 7 + 3 + 1 (regrouped) = 11 (regroup the 1)
  3. Add the hundreds place: 1 (regrouped) = 1
  4. Write the final answer: 114

Common Mistakes to Avoid

  • Forgetting to regroup when the sum exceeds 9
  • Writing the regrouped digit in the wrong place value
  • Failing to include the regrouped digit in the next place value calculation

👍 Note: Practice makes perfect. Be sure to work through multiple examples to reinforce your understanding of double digit addition with regrouping.
