Addition is the process of combining two or more numbers to find a total or sum. When working with larger numbers, students may need to regroup digits to make calculations easier.
Example:
5678 + 1234 = 6912
Let’s break it down step by step:
- Start with the ones place: 8 + 4 = 12 → write 2, carry 1
- Move to the tens place: 7 + 3 = 10, plus the carried 1 = 11 → write 1, carry 1
- Move to the hundreds place: 6 + 2 = 8, plus the carried 1 = 9
- Move to the thousands place: 5 + 1 = 6.
Final answer: 6912

This process is called regrouping or carrying, and it helps students manage larger numbers accurately.
