Introduction

Multiplication is a fundamental operation in mathematics that involves finding the product of two or more numbers. In this article, we will explore how to solve multiplication problems using the box method, also known as the lattice method or the grid method. This method is particularly useful for multiplying large numbers and can be a valuable tool for students and professionals alike.

What is the Box Method?

The box method is a visual representation of multiplication that involves breaking down the problem into smaller parts and using a grid or box to organize the calculations. This method is based on the concept of the distributive property, which states that a single operation can be distributed over multiple operations.

Step-by-Step Guide to Using the Box Method

To use the box method, follow these steps:

Write the problem: Write the multiplication problem in the form of a grid or box, with the numbers to be multiplied on the top and side of the box.
Break down the problem: Break down the problem into smaller parts by multiplying the numbers in the top row by the numbers in the side column.
Calculate the products: Calculate the products of the numbers in the top row and side column, and write the results in the corresponding boxes.
Add the products: Add the products of the numbers in the top row and side column to find the final answer.

Example 1: 1.4872 × 9

Let's use the box method to solve the problem 1.4872 × 9.

Step 1: Write the problem

	1	4	8	7	2
9

Step 2: Break down the problem

To break down the problem, we need to multiply the numbers in the top row by the numbers in the side column.

	1	4	8	7	2
9	1 × 9 = 9	4 × 9 = 36	8 × 9 = 72	7 × 9 = 63	2 × 9 = 18

Step 3: Calculate the products

Now, we need to calculate the products of the numbers in the top row and side column.

	1	4	8	7	2
9	9	36	72	63	18

Step 4: Add the products

Finally, we need to add the products of the numbers in the top row and side column to find the final answer.

	1	4	8	7	2
9	9	36	72	63	18
	9	36	72	63	18
