The operation to perform:
860 - 338 + 309

Add the positive numbers together.

The operation to perform:
860 + 309

Method used below: column adding, from right to left (traditional).


Stack the numbers on top of each other.

The ones digits line up in the first column from the right.

The tens digits line up in the next column to the left.

And so on...


  860
+  309

?

Add column by column; start from the column on the right.

Add the digits in the ones column:

0 + 9 = 9

9 is the ones digit.
Write it down at the base of the ones column.


   
  860
+  309

    9

Add the digits in the tens column:

6 + 0 = 6

6 is the tens digit.
Write it down at the base of the tens column.


  
  860
+  309

   69

Add the digits in the hundreds column:

8 + 3 = 11

How did we add the digits? Explanation below.

Group the ones together in order to make tens:


8 + 3 =


8 + 3 =


8 + 2 + 1 =


8 + 2 + 1 =


10 + 1 =


11


Change the order in which the numbers are added, the sum stays the same.
Break some number(s) into component parts, the sum stays the same.


The sum is a two-digit number: 11.


1 is the hundreds digit.
Write it down at the base of the hundreds column.


1 is the thousands digit.
Write it down at the base, next to the hundreds digit.

 1169

Answer:
860 + 309 = 1,169

The initial operation has become:

860 - 338 + 309 =


1,169 - 338

Now subtract the final numbers above:
1,169 - 338 = ?

Method used below: column subtracting, from right to left (traditional)


Stack the numbers on top of each other.

The ones digits line up in the first column from the right.

The tens digits line up in the next column to the left.

And so on...

Subtract column by column; start from the column on the right

Subtract the digits in the ones column:

9 - 8 = 1.
1 is the ones digit.
Write it down at the base of the ones column.

Subtract the digits in the tens column:

6 - 3 = 3.
3 is the tens digit.
Write it down at the base of the tens column.

Subtract the digits in the hundreds column:

1 - 3 = ?

The second digit is larger than the first.
Borrow from the next column to the left.

The borrowing is a two step process:


Subtract 1 from the top digit in the column of the thousands: 1 - 1 = 0.
Cross out the top digit you've borrowed 1 from: 1.
Write the answer above that digit: 0.


When borrowing, 1 thousand = 10 hundreds.
Add 10 to the top digit in the column of the hundreds: 10 + 1 = 11.


 0   
 11169
-  338

   31

After borrowing, the subtraction has become:
11 - 3 = 10 + 1 - 3 = 10 + 1 - 3 = 1 + (10 - 3) = 1 + 7 = 8.
8 is the hundreds digit.
Write it down at the base of the hundreds column.


 0   
 11169
-  338

  831

Subtract the digits in the thousands column:

There is a single digit in this column: 1 0.
0 is the thousands digit.
Write it down at the base of the thousands column.


 0   
 11169
-  338

 0831

Leading zeros

When leading zeros occupy the most significant digits of a natural number, they could be left blank and the numeric value stays the same:

0831 = 831

Final answer:
860 - 338 + 309 = 831
