Question

Alan multiplies a 4-digit number by 36. How can you tell the

number of partial products Alan will have?

Answer 1

Explanation:

The number of partial products in this calculation will be equal to the number of digits in the 4-digit number being multiplied by 36. Since 36 has two digits, there will be 2 partial products for each digit in the 4-digit number, for a total of 2 * 4 = 8 partial products.
