A grid is drawn up, and each cell is split diagonally. The two multiplicands of the product to be calculated are written along the top and right side of the lattice, respectively, with one digit per column across the top for the first multiplicand (the number written left to right), and one digit per row down the right side for the second multiplicand (the number written top-down).
During school on a cold winter's day, a young girl's thoughts about the multiplication of 8 revolve around winter games, particularly ice skating. The video briefly explores the distributive property of multiplication/addition for multiplying 8 by numbers higher than 10, and closes by noting the numeral 8's resemblance to a sideways infinity ...
The number 731 would be represented by 7s, 3s, E. The number 804 would be represented by 8s, X, 4L. The number 1493 would be represented by 1s, 4s, 9s, 3L. Since the ones position on quipu cords are shown in a distinctive way (i.e., using long knots and figure-eight knots), it is usually clear where a number ends.

It was considered the height of Colonial maths education [ 2 ] and still figures in the French national curriculum for secondary education, [ 3 ] and in the primary education curriculum of Spain.
There is no natural interpretation of multiplying vectors to obtain another vector that works in all dimensions, however there is a way to use complex numbers to provide such a multiplication. In a two-dimensional cartesian plane, identify the point with coordinates (x, y) with the complex number z = x + iy.
