What is the box method in multiplication?

Back

The box method is a visual way to multiply numbers by breaking them into parts (or boxes) to simplify the multiplication process.

What are partial products?

Back

Partial products are the results of multiplying each part of the numbers separately before adding them together to get the final product.

How do you use the box method for 170 x 5?

Back

Break 170 into 100, 70, and 0. Multiply each by 5: (100x5) + (70x5) + (0x5) = 500 + 350 + 0 = 850.

What is the first step in using the box method?

Back

The first step is to break each number into its place values.

How do you find the product of 129 x 4 using partial products?

Back

Break 129 into 100, 20, and 9. Multiply each by 4: (100x4) + (20x4) + (9x4) = 400 + 80 + 36 = 516.

What is the product of 619 x 2 using the box method?

Back

Break 619 into 600, 10, and 9. Multiply each by 2: (600x2) + (10x2) + (9x2) = 1200 + 20 + 18 = 1238.

How do you calculate 82 x 4 using partial products?

Back

Break 82 into 80 and 2. Multiply each by 4: (80x4) + (2x4) = 320 + 8 = 328.

Front

What is the final step after finding partial products?

Back

The final step is to add all the partial products together to get the total product.

What is the product of 324 x 7 using the box method?

Back

Break 324 into 300, 20, and 4. Multiply each by 7: (300x7) + (20x7) + (4x7) = 2100 + 140 + 28 = 2268.
