IMPORTANT FACTS ABOUT BOX MULTIPLICATION METHOD
Place value - Essential tip for understanding box method
To better understand the Box Method, we must first of all have a basic understanding of place value. In mathematics, place value is the value of each digit in a number, based on its position. Given for instance the number 4852, where is the place value of each digit in that number?
Hey, it's easy to find out. It goes thus;
- 4 is in the "thousandth's" position, so its place value is 4000.
- 8 is in the "hundredths" position, so its place value is 800.
- 5 is in the "ten's" position, so its place value is 50.
- 2 is in the "unit" position, so its place value is 2.
As each factor is broken up into expanded form, children can best understand the place value of each digit.
Hey now, you've got to worry less about multiplying larger digit numbers, for our worksheets consist of well-designed area model multiplication examples and test.
It is very easy.
You simply need to draw a box or an array, with columns and rows proportional to the number of digits or size of numbers to be multiplied. As per the examples, we'll solve below 2 by 1 digits, 3 by 2 digits and 4 by 3 digits.
Example 1. 2 digit multiplication: Box method | Multiplying 2 digit by 1 digit
Multiply 19 x 3
Huh! We are going to gradually follow the steps below;
In the first place, we find the place value of 19 and 3.
19 x 3 = (10 + 9) x 3
Secondly, we now draw a box of 2 columns (for 10 and 9) and 1 row (for 3).
Thirdly, write the expanded form at the top (10 and 9) and on one side (3) of the box.
Fourthly, it's time to multiply. Hey, we're multiplying only the numbers that meet in each space.
Lastly, we add up all the smaller products to make our final product;
Hurray! Yes I got it so easily.
So, 19 x 3 = 57
Example 2. 4 digit multiplication: Box method | Multiplying 4 digit by 3 digit
Multiply 1245 x 742
Hmmm, the multi digits seems difficult right! Not to bother.
Using the box method is very easy and will make you obtain the correct answer with no stress.
As usual, we find the place value of the given factors.
1245 x 742 = (1000 + 200 + 40 + 5) x (700 + 40 + 2)
That means we have a box of 4 colums and 3 rows.
Secondly, we draw our box of 4 columns (for 1000, 200, 40 and 5) and 3 rows (for 700, 40 and 2)
Thirdly, write the expanded form at the top (1000, 200, 40 and 5) and on one side (700, 40, 2) of the box.
Next, we place our 4 factors (1000, 200, 40, 5) on each column and by each row, we place our 3 factors (700, 40, 2).
After placing the factors, we begin multiplying. Hey, multiply only factors that meet in each space.
Ultimately, we now add up all the smaller products to make our final product;
Holaaaaa. I got my answer correctly.
Box method is very simple.
