How to Multiply Using the Box Method Step-by-Step

TL;DR

To multiply two numbers using the box method, create a box with columns and rows based on the digits of the numbers. Break the numbers into their place values, multiply the corresponding parts, and fill the box with the results. Finally, add all the products within the box to get the final answer.

Transcript

in this video we're going to talk about how to multiply two numbers using the box method so for the first example we have 56 * 49 now this is a two-digit number and this is a two-digit number so we need to create a box that's going to have two columns and two rows so those are the two columns and here we have two rows 56 is 50 + 6 so we're going to...

Questions & Answers

Q: What is the box method of multiplication?

The box method is a visual method for multiplying two numbers. It involves creating a box with columns and rows corresponding to the number of digits in the two numbers being multiplied.

Q: How do you expand the digits within the box?

To expand the digits, you break apart each number into its individual place values. For example, 56 would be expanded as 50 + 6, and 49 would be expanded as 40 + 9.

Q: How do you multiply the numbers within the box?

Within the box, you multiply the digits in each corresponding cell. For example, to find the product of 50 * 40, you multiply 5 * 4 to get 20 and add two zeros to get 2,000.

Q: How do you find the final product of the two numbers?

To find the final product, you add up all the numbers within the box. The order in which you add them does not matter. In the example, the sum is 2,000 + 350 + 240 + 42, which equals 2,632.

Summary & Key Takeaways

• The box method involves creating a box with a number of columns and rows equal to the number of digits in the two numbers being multiplied.

• The digits of each number are then expanded and multiplied within the box, with zeros added as placeholders.

• The final step is to add up the numbers within the box to get the product of the two numbers.
