Box multiplication method
This algorithm is sometimes also called the grammar school method because it is often taught in mathematics education at the level of primary school or elementary school.
Step 1: Make a table with the place values of the first factor at the top and the place
values of the second factor on the left.
Step 2: Multiply the place values. Enter the products in the table.
Step 3: Sum up the values in the row of the table.
Step 4: Add the row sums. This will result in the product of the original numbers.
Let's solve this by following the steps above
Step 1
Make a table with the place values of the first factor at the top and the place
values of the second factor on the left.
Step 2
Multiply the place values. Enter the products in the table.
Simplify the table as shown below.
Step 3
Sum up the values in the row of the table.
Step 4
Add the row sums. This will result in the product of the original numbers.
