It’s not clear wether it’s asking for the product of two number that were given or to give instructions to explain finding a product using standard algorithm. I’ll go with the second one. First you set it up for the two number to be lined up neatly, then you need to multiply the last number with the one above it and continue to multiply with the higher numbers, next if there is anymore digits you must put a zero below and continue what you did with first digit.
