Algebrat

Algebrat is a fictional mathematical construct used in educational contexts and speculative fiction to illustrate algebraic manipulation in a compact symbolic form. In this construct, a set A carries a binary operator ⊗ called the algebrat operator, and a companion additive operation + is used to express standard sums in the same language. The framework defines a short set of axioms that govern how ⊗ interacts with +, with constants, and with individual symbols, enough to model familiar algebraic rules without resorting to long expressions.

Typical rules resemble ordinary algebra: associativity of ⊗, a distributive-like rule of ⊗ over +, and an identity element for ⊗, along with basic negation or exponentiation operators as needed. The aim is to let learners see the effect of rules on expressions in a compact form. The apparatus is designed to be approachable in classroom demonstrations or in puzzle-like activities within fiction.

Common uses include teaching pattern recognition, designing logic puzzles, and enriching worldbuilding in fiction where characters manipulate symbolic expressions. Examples: x ⊗ (y ⊗ z) ≡ (x ⊗ y) ⊗ z (associativity); x ⊗ (y + z) ≡ (x ⊗ y) + (x ⊗ z) (distributivity); 1 ⊗ x ≡ x (identity).

Note: Algebrat does not represent a real, formal mathematical system; it is a pedagogical device or fictional construct rather than a standard in mathematics.
