To understand multi-digit addition, you can use the following steps:
-
Align the Numbers: Write the numbers you want to add vertically, aligning them by their place values (ones, tens, hundreds, etc.).
Example:
256 + 347
-
Add from Right to Left: Start adding the numbers from the rightmost column (the ones place) and move to the left.
-
Carrying Over: If the sum of a column is 10 or greater, carry over the extra value to the next column to the left.
-
Sum Each Column: Write down the sum for each column, including any carried value.
Example Problem
Let's solve the addition of 256 and 347 using these steps.
256
+ 347
------
-
Ones Place: 6 + 7 = 13. Write down 3 and carry over 1.
(carry 1) 256 + 347 ------ 3
-
Tens Place: 5 + 4 = 9, then add the carry-over 1: 9 + 1 = 10. Write down 0 and carry over 1.
(carry 1) 256 + 347 ------ 03
-
Hundreds Place: 2 + 3 = 5, then add the carry-over 1: 5 + 1 = 6.
(carry 0) 256 + 347 ------ 603
-
Final Sum: The total is 603.
Using this method allows you to systematically add multi-digit numbers without skipping steps or making errors.
