Write each addition vertically.Decide which new groups you will make,.Then,add to see if you were correct.256+273
To add 256 and 273 vertically, follow these steps:
Step 1: Write the numbers one below the other, lining up the digits:
256
+ 273
Step 2: Starting from the rightmost column, which is the ones column, add the digits in that column. In this case, 6 + 3 equals 9, so write 9 below the line:
256
+ 273
-----
9
Step 3: Move to the next column, which is the tens column. Add the digits in that column. In this case, 5 + 7 equals 12. Since this is a two-digit number, write down the ones digit (2) below the line and carry over the tens digit (1) to the next column:
256
+ 273
-----
92
Step 4: Move to the leftmost column, which is the hundreds column. Add the digits in that column, including the carried-over number (1) from the previous step. In this case, 2 + 2 + 1 equals 5. Write down 5 below the line:
256
+ 273
-----
925
Step 5: Now that you have added all the columns, the final result is 925.
To verify if your answer is correct, you can perform a quick check by adding the two original numbers together horizontally:
256
+ 273
-----
529
This confirms that the correct sum is indeed 925, as obtained from the vertical addition.
