partial product

Rounding is the process of adjusting the digits of a number to make it simpler while keeping its value close to what it was. It often involves increasing or decreasing the number to the nearest ten, hundred, etc.

To round a number to the nearest ten, look at the digit in the ones place. If it is 5 or greater, round up. If it is less than 5, round down.

Partial products are the results of multiplying each digit of one number by each digit of another number, then adding those results together.

Break down 28 into 20 and 8. Then calculate (4 x 20) + (4 x 8) to find the partial products.

The first step is to break down one or both of the numbers into their place values.

(6 x 80) + (6 x 4) are the partial products for 6 x 84.

Add all the partial products together to find the total.

The result of rounding 36 to the nearest ten is 40.

The result of 87 x 4 using partial products is 348.

Using partial products simplifies the multiplication process, making it easier to understand and calculate, especially for larger numbers.
