## Column Method – Definition With Examples

We use the column method for three basic operations i.e.addition, subtraction and multiplication.

## For example:

## Why is Place Value Important in the Column Method?

Let’s look at the example below and use column addition.

- First, the numbers are lined up one above the other.
- Secondly, we add the ones and write the answer.

- The third step is to regroup the tens under the tens column. In $14$, the digit $1$ is the value of the tens.
- Add the digits at the tens place. In our example, $8 + 1 = 9$, but we add 1 from under the line. So the answer for the tens is $9$.

## The Expanded Column Method

For example, the number $782$ can be broken down into: $700 + 80 + 2$

The expanded method is an addition sum is carried out in the following way:

Suppose, we have to add $47 + 134$

Firstly, we will expand $47 and 134$.

$47 = 40 and 7 and 134 = 100, 30 and 4$

Now we sort the numbers into hundreds, tens, and ones and add them in their groups.

In this example, we add $30 + 40 + 10 = 80$

In this example, we add $100 + 0 = 200$

Now, we add all of our digits together, we get $100 + 80 + 1 = 181$

Another example is given below:

Let us take an example of an expanded column method of subtraction.

## The Column Method for Subtraction without Borrowing

Sometimes we don’t have to borrow the digits from a column in subtraction.

The first step is to sort your numbers into tens and ones:

We should always place the biggest numbers in the top row of the columns.

Now you can subtract the numbers in each column:

The answer to the sum is $76 – 42$ is $34$.

## The Column Method for Addition without Borrowing

We use the column method for addition without borrowing or carrying any values between columns.

Now, put the values into their columns:

Next, we add up all of your values within their groups.

Therefore, the answer to the sum $262 + 615$ is $897$.

## The Column Method of Multiplication

When we multiply two numbers using the column method multiplication, we use the following steps:

Suppose we are multiplying $96$ and $36$.

Step I: We multiply the multiplicand $(96)$ by the ones digit of multiplier $(6)$ i.e.,

Step III: The next step is to add the partial products i.e.,

Partial product $1 (576 ones) +$ Partial product $2 (288 tens)$

Now we shall apply the same method for multiplying a $3-$digit number by a $2-$digit number.

Let’s take another example. Find the product of $145$ times $12$ using the column method.

1. Find the error in the following.

2. Find the value of ‘A’ in the following.

Answer: Cost of 1 necklace $=$ Rs $342$

Cost of $23$ necklaces $= 342 ✕ 23 =$ Rs $7866$

Cost of $23$ necklaces $= 6000 + 900 + 800 + 120 + 40 + 6 =$ Rs $7866$
