## Short Multiplication

In this video, Mr. Squeaks decides to make a new invention out of spare parts. When he turns it on there's just one problem, all it displays is multiplication equations! If you don’t how to do multiplication using short method multiplication, don’t worry! This video on column method for multiplication explains what is standard algorithm in multiplication, and how to do multiplication column method. Let's help Mr. Squeaks unlock his invention by practising short and long multiplication!

## Multiplication Column Method

What is the column method in multiplication? When we want to answer the question, how do you do long and short multiplication? We need to first understand the column method. We can solve addition, subtraction and multiplication problems using different column methods. Solving multiplication with the columns method is a step-by-step way to solve a multiplication problem. We can use it to multiply by 1 digit and 2 digit numbers, or even more. Read on to find out how to find the answer to the question: how do you do long and short multiplication?

## Multiplication Column Method – Example

Let’s look at some examples to find out how to do short multiplication using column method. Let’s take a look at a column method multiplication example so we can see how to do multiplication column method.

In this short multiplication example, we will be multiplying fifty-two times four.

Before we can do multiplication using column method, we must set up the problem by placing the larger factor on top, and line up the other factor below it. We must line up all the digits by place value, and include a multiplication symbol.

Now that our problem is set up for column multiplication, let’s solve it!

In order to calculate fifty-two times four first, multiply the bottom factor by the ones place, regrouping as needed. Four times two is eight, so we write it in the ones place.

No regrouping is needed, so we move on to the next step. Next, multiply the bottom factor by the tens place. What is the product of four times five tens? Twenty tens, and we write it in the tens and hundreds place.

When we solve fifty-two times four we get the product two hundred! We just did column method multiplication! Now that you have practised and know how to do column method multiplication, let’s review!

## Multiplication Column Method – Summary

Remember, long multiplication column method is a way of using the column method to solve a multiplication by 2 or more digits. Using the multiplication column method for short multiplication means multiplying by 1 digit.

Here are the steps for how to do multiplication column method:

Step # What to do?
1 Set up the equation vertically
by lining up the place values.
2 Multiply the bottom factor by the
ones place, regrouping as needed.
3 Multiply the bottom factor by the
tens place, regrouping as needed.
4 Repeat the pattern as needed until
you have multiplied all the place values.

Follow these simple steps if you want to practise multiplication with standard algorithm!

### TranscriptMultiplication (Column Method)

One afternoon long long ago, Mr. Squeaks decided to make a new invention out of spare parts. There's just one problem, all it displays is multiplication equations! Let's help Mr. Squeaks unlock his invention by multiplying up to three digits using the column method. The first equation we need to solve to help Mr. Squeaks is fifty-two times four. When we multiply numbers using the column method we place the larger number on top, and line up the other number below it. We must line up all the digits by place value, and include a multiplication symbol. In order to calculate fifty-two times four first, multiply the bottom factor by the ones place. Four times two is eight so we write it in the ones place here. Next move on to the next column. What is the product of four times five tens? Twenty tens, and we write it here. The product of fifty-two times four is two hundred and eight. Mr. Squeaks enters the product on the robot and another equation appears! Now, we'll calculate eighty-six times nine. First, set up the equation vertically by lining up the place values. Then, multiply the bottom factor by the ones place. What is the product of nine times six? Fifty four, so we write four in the ones column and a five in the tens column, as fifty ones is equal to five tens. Next, multiply the bottom factor by the tens place. What is the product of nine times eight tens? Seventy-two tens. Since we carried five tens to the tens place, we must add them on. Seventy-two tens plus five tens is seventy-seven tens. The product of eighty-six times nine is seven hundred and seventy-four. Mr. Squeaks enters the product on the robot, and one final equation appears! Lastly, we'll calculate two hundred and ninety-three times seven. First, set up the equation vertically by lining up the place values. Next, multiply the bottom factor by the ones place and make an exchange if the answer is two digits. What is the product of seven times three? Twenty-one, so we put one in the ones place and carry two tens here, as we can exchange twenty ones for two tens. Then, multiply the bottom factor by the tens place. What is the product of seven times nine tens? Sixty-three tens. Now, add the two tens we carried over after our exchange. Sixty-three plus two is sixty-five so we put five in the tens place and exchange our sixty tens for six hundreds, writing it in the hundred column. What do we do next? We multiply seven times two hundred to get fourteen hundreds. Then add on the six we carried over. Forteen plus six is twenty and we write it here. Remember to put a comma, starting after the ones and counting back three spaces. The product of two hundred and ninety-three times seven is two thousand and fifty-one! Remember when we multiply numbers up to three digits using the column method the first step is to set up the equation vertically by lining up the place values. The second step is to multiply the bottom factor by the ones place, making an exchange and carrying the digit over to the next column as needed. The third step is to multiply the bottom factor by the tens place, making an exchange if needed. The fourth step is to repeat the pattern until you have multiplied all the place values. Okay Mr. Squeaks, is your invention working? Mr. Squeaks has a new robot friend and it looks like he's called them Imani! What would you name his new friend? Write your name ideas in the comments below!
