A method of multiplying where each place value digit is multiplied separately and the results are added is known as what?

Explanation:
This is about using partial products. In this method you break one number into its place-value parts and multiply each part by the other number, then add all those results together. It relies on the distributive property: a(b + c) = ab + ac, which is why you can multiply 23 by 45 by doing 23 × 5 to get 115 and 23 × 40 to get 920, then add them to get 1,035. The approach shows how each digit’s value contributes to the final product. Other options don’t fit because they aren’t names for a multiplication method. Forward roll, blood sugar, and metacognitive skills refer to unrelated concepts.
