The work *+0-0 (add nothing, subtract nothing)* starts from a simple shape, and does two simple things:

- cut the shape in half,
- and either rotate half of the shape by 90° or move half of the shape.

A simple start, simple operations, yet what emerges after enough repetitions isn’t simple.

Complexity is created without adding or removing anything.

A sequence of operations like this, with discrete steps, repetitions, and conditional choices is called an *algorithm*, from the name of the 9th-century mathematician al-Khwārizmī.

Similar to a recipe to be followed, the concept of an algorithm is a fundament in *computer science* today.

The algorithm does not “see” or “know” the shape. It cannot lift the shape, push it or turn it around like we would with a set of blocks.

Eyeless, handless, to make it work, shapes have to be represented in a language it understands.

Mathematics provides us with that language.
