?

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

Add the digits in the ones column:

7 + 1 + 5 = 13

How did we add the digits? Explanation below.

Group the ones together in order to make tens:


7 + 1 + 5 =


7 + 1 + 5 =


7 + 6 =


7 + 6 =


7 + 3 + 3 =


7 + 3 + 3 =


10 + 3 =


13


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: 13.


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


1 is the tens digit.
Carry it over to the tens column.
Write the digit above that column.
Add it with the rest of the digits in that column.

How did we add the digits? Explanation below.

Group the ones together in order to make tens:


9 + 9 + 5 + 1 =


9 + 9 + 5 + 1 =


(9 + 1) + 9 + 5 =

10 + 9 + 1 + 4 =


10 + 10 + 4 =


10 + 10 + 4 =


20 + 4 =


24



The sum is a two-digit number: 24.


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

Answer:
937 + 1,951 + 515 = 3,403

The initial operation has become:

937 + 1,951 + 515 - 305 =


3,403 - 305

Now subtract the final numbers above:
3,403 - 305 = ?

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:

3 - 5 = ?

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

In this case we borrow across zero(s), a multiple step process:


Subtract 1 from the top digit in the column directly to the left.
But that digit is zero. You need to go further left.


Subtract 1 from the nearest column to the left with a non-zero top digit.
That is the column of the hundreds: 4 - 1 = 3.
Cross out the top digit you've borrowed 1 from: 4.
Write the answer above that digit: 3.


Cross out the zero(s) that you were going across to the left: 0.
Write a 9 above each one of the crossed out zeros.
Why? In fact we have subtracted 1 from 40: 40 - 1 = 39.


When borrowing, 1 ten = 10 ones.
Add 10 to the top digit in the column of the ones: 10 + 3 = 13.

 34013
-  305

     

After borrowing, the subtraction has become:
13 - 5 = 10 + 3 - 5 = 10 + 3 - 5 = 3 + (10 - 5) = 3 + 5 = 8.
8 is the ones digit.
Write it down at the base of the ones column.

Subtract the digits in the tens column:

0 9 - 0 = 9.
9 is the tens digit.
Write it down at the base of the tens column.

Subtract the digits in the hundreds column:

4 3 - 3 = 0.
0 is the hundreds digit.
Write it down at the base of the hundreds column.

Subtract the digits in the thousands column:

There is a single digit in this column: 3.
3 is the thousands digit.
Write it down at the base of the thousands column.

-  305

 3098

Final answer:
937 + 1,951 + 515 - 305 = 3,098
