Simple Addition Example:

Example 1: Let's take the example of adding 57 and 38
   57
+  38
------
Step 1: Start by adding the digits in the rightmost column (the ones place):

   57
+  38
------
    5 (7 + 8 = 15; write down 5 and carry over 1)


Step 2: Move to the next column (the tens place) and add the carried-over value:


   57
+  38
------
   95 (Carry over: 1 + 5 + 3 = 9)

So, the sum of 57 and 38 is 95.

Example 2:
Sure, let's add two more two-digit numbers together.
Let's add 46 and 29:

   46
+  29
------
Step 1: Start by adding the digits in the rightmost column (the ones place):
   46
+  29
------
    5 (6 + 9 = 15; write down 5 and carry over 1)


Step 2: Move to the next column (the tens place) and add the carried-over value:


   46
+  29
------
   75 (Carry over: 1 + 4 + 2 = 7)

So, the sum of 46 and 29 is 75.

Example 3: Let's take the example of adding 357 and 489
357 + 489 = ?

   357
+  489
-------

Step 1: Start by adding the digits in the rightmost column (the ones place):

   357
+  489
-------
     6 (7 + 9 = 16; write down 6 and carry over 1)

   357
+  489
-------
    46 (Carry over: 1 + 5 + 8 = 14; write down 4 and carry over 1)

Step 3: Move to the next column (the hundreds place) and add the carried-over value:

   357
+  489
-------
   846 (Carry over: 1 + 3 + 4 = 8)

So, the sum of 357 and 489 is 846.

Example 4: Let's add two more three-digit numbers together 624 and 739.

Let's add 624 and 739:


   624
+  739
-------
Step 1: Start by adding the digits in the rightmost column (the ones place):

   624
+  739
-------
     3 (4 + 9 = 13; write down 3 and carry over 1)

Step 2: Move to the next column (the tens place) and add the carried-over value:

   624
+  739
-------
    63 (Carry over: 1 + 2 + 3 = 6)

Step 3: Move to the next column (the hundreds place) and add the carried-over value:

   624
+  739
-------
  1363
So, the sum of 624 and 739 is 1363.
