To write each addition vertically, you can stack the numbers one on top of the other, aligning the units, tens, hundreds, etc. Here's how you can proceed with the given addition:

2 5 6
+ 1 2 7 3
________________

To determine the new groups, you need to consider the place value of each digit. The units place does not require any new group, as the sum of the digits in this position (6+3 = 9) does not exceed 10. Now, let's check the other place values:

New Ten: In the tens place, when you add 5 with 7, the sum exceeds 10. To form a new group, you need to carry over the excess value. So, you write down the leftover (2) in the tens place (since 12-10 = 2) and carry over 1 to the hundreds place.

2 5 6
+ 1 2 7 3
________________
2 7 7

New Hundred: In the hundreds place, you need to add the carried over 1 with the digit in that place (2+1 = 3). The result (3) will be placed in the hundreds place.

2 5 6
+ 1 2 7 3
________________
3 2 7 7

New Thousand: Since there is no carried over value from the hundreds place, the sum will be the same as the digit in the thousands place. Therefore, in this case, there is no new thousand.

To check if you were correct, you can add vertically by simply adding the digits in each place value:

2 5 6
+ 1 2 7 3

Sum: 1 5 9 2 9

The sum comes out as 1,5929, confirming that the vertical addition was correct.
