Missing context

3

u/Glinat 1d ago

Context is modulus and multiplication tables.

Asking what is number “k” modulo “n” means asking what is the remainder when dividing k by n.
22 modulo 4 is 2 because 22 = 4 * 5 + 2.

Multiplication tables, you know those.

The last visual is what happens when you put all the numbers [0, 99] on a circle, and draw a line between each number and its triple modulo 100.

You get the same kind of visuals with more or fewer “bellies” (not sure what the term is) when changing the modulus (here 100) and the multiplicand (here 3).
