Here is an example of addition with regrouping for grade 2:

Problem: 34 + 27

Step 1: Start by adding the ones place. 4 + 7 = 11. Write down the 1 and carry over the 10 to the tens place.

Step 2: Add the tens place. 1 (carried over) + 3 + 2 = 6. Write down the 6.

Step 3: Combine the tens and ones place. The final answer is 61.

So, 34 + 27 = 61.
