write each addition vertically.Decide which new groups you will make .Then add to see if you were correct .256+273
Is this what you are asking?
256
+273
______
529
To write the addition vertically, start by arranging the two numbers one below the other, aligning the digits according to their place value:
256
+273
Next, begin by adding the digits in the rightmost column, which represents ones place:
256
+273
-----
529
The sum of the digits in the ones place is 9, so we write down 9 and carry over the 1 to the next column. Now we move to the next column, which represents tens place:
256
+273
-----
529
Adding the digits in the tens place, 5 and 7, along with the carried over 1, gives us 13. We write down 3 in the tens place and carry over the 1 to the next column. Finally, we move to the last column, which represents hundreds place:
256
+273
-----
529
Adding the digits in the hundreds place, 2 and 2, along with the carried over 1, gives us 5. We write down 5 in the hundreds place. Since there are no more columns left, we have completed the addition.
To verify the correctness of our answer, we can simply add the two numbers horizontally:
256
+273
-----
529
As the sum of the digits in each column matches the correctly written vertical addition, we can conclude that our answer, 529, is correct.
