This image could be re-created using vector graphics as an SVG file. This has several advantages; see Commons:Media for cleanup for more information. If an SVG form of this image is available, please upload it and afterwards replace this template with {{vector version available|new image name}}. It is recommended to name the SVG file "Multiplication as scaling integers.svg" - then the template Vector version available (or Vva) does not need the new image name parameter.

Disgrifiad
English: Multiplication is often taught as repeated addition. A more accurate representation is to think of it as scaling quantities. This animation illustrates this. Notice that the blue dot in the blue segment of length 3 is placed at position 1, and the blue segment is scaled so that this dot is placed at the end of the red segment, of length 2. For multiplication by any X, the blue dot will always start at 1 and end at X. This works even for X smaller than 1.
