Multiplication mod 100

This short animation shows multiplication by k modulo 100 where k ranges from 2 to 51. To visualize this, we draw 100 equally spaced dots on the circle and label them from 0 to 99. For a fixed value of k, we connect each i to k*i modulo 100 by a line. If you like this video, consider subscribing to the channel or consider buying me a coffee: Thanks! Here is a longer, wide format, slower version (with synthwave music) If you want more information about this, check out this amazing video by ​⁠ mathologer: , which also has a great visualization at the end.
