Math

Explanations of the math behind SPIRA SUURA's tools, such as the Dot Mandala Generator. Move the pictures and see for yourself.

Dot patterns in a circle

How can you place dots of the same size in a circle without overlap? Move the dot size and compare how many fit with each of eight layouts.

• Compare eight layouts Move the dot size and see at once how many dots fit with each of the eight layouts.

Colors and numbers

We look at the colors collected in the "Number Colors" survey with the eyes of math.

• Where colors gather Do the colors felt for the same digit gather together? Watch colors being sorted into groups of similar ones in 3D, one step at a time.
