What is the product of 315 and 4 using the partial products method?

Answer explanation

The product of 315 and 4 using the partial products method is calculated by multiplying each digit of the first number (315) by the second number (4). This gives 1200 (300*4), 60 (15*4), and 20 (5*4). Adding these partial products together gives the total product, which is 1260, not 126.
