Multi-digit multiplication is the process of multiplying numbers that have two or more digits, which involves breaking down the numbers into smaller parts and using the distributive property to find the product.

To calculate the total amount raised from donations, multiply the number of donors by the amount each donor contributes.

The total number of packets used is calculated by multiplying the number of boxes by the number of packets in each box.

The product of 726 and 23 is 16,698.

To perform multi-digit multiplication using the standard algorithm, align the numbers vertically, multiply each digit of the bottom number by each digit of the top number, and then add the results, taking care to shift left for each new row.

The distributive property states that a(b + c) = ab + ac, which allows for easier calculations by breaking down complex multiplication into simpler parts.

You can check the accuracy of a multiplication problem by using the inverse operation, division, to see if dividing the product by one of the factors returns the other factor.
