Multiplication Worksheet Generator

Printable worksheets of multiplications written in columns, from a two-digit number times a one-digit number to a four-digit number times a three-digit number, in 6 levels: twenty per page, or sixteen when the second number has two or three digits. Every worksheet also has its answer key, with the carries, the partial products and the products.

Long multiplication is the written method for multiplying numbers too large to multiply in your head. You multiply the top number by each digit of the bottom number, starting with the ones, and write each result, called a partial product, on its own line: the one for the tens digit is worth ten times more, and the one for the hundreds digit a hundred times more. Then you add the partial products. It puts the times tables, place value and column addition to work together. The answer key shows every carry and, with a two- or three-digit bottom number, every partial product and their sum, so you can see exactly where a mistake slipped in.
