To perform the addition vertically, we align the numbers according to place value:
256
+1273
______
First, let's add the ones place: 6 + 3 = 9. Write down 9 under the line.
256
+1273
______
9
Next, let's add the tens place: 5 + 7 = 12. Since 12 is a two-digit number, we write down 2 in the tens place and carry over the 1 to the hundreds place.
256
+1273
______
29
Now, let's add the hundreds place: 2 + 2 + 1 (carried over) = 5. Write down 5 in the hundreds place.
256
+1273
______
529
Finally, we add the thousands place: 0 + 1 (carried over) = 1. Use a separate line to write down 1 in the thousands place.
256
+1273
______
1529
To check if our addition is correct, we can add the original numbers horizontally:
256
+ 1273
_______
1529
The sum is 1529, so our answer is correct.
New groups created:
- There was no need for creating a new ten since the sum of the ones place (6 + 3) was less than 10.
- We created a new hundred when the sum of the tens place exceeded 10.
- We also created a new thousand when the sum of the hundreds place exceeded 10.
