A weird way of doing long multiplication...but it's amazing still. Lines are drawn representing the digits in the problem. The number of intersections at particular points gives the answer to the multiplication question. Pen and paper - no narrative.... (01:14)

Students learn to multiply numbers with one or more digits, such
as 56 x 7. The first step is to line up the numbers vertically so that
the units digits are in the same column. Next, multiply 6 x 7 to get
42, which is the same as 4 tens and 2 ones.... So put a 2 in the units
column and carry a 4 to the tens column. Next, multiply 5 x 7 to get
35, then add the 4 that was carried to the tens column to get 39. So 56 x 7 = 392. Note that the answer to a multiplication problem is called the product, so the product of 56 x 7 is 392. Students also learn to multiply numbers with two or more digits, such as 21 x 43, by creating two rows of products and adding the rows. (01:56)
