numaral

Numaral is a hypothetical numeral system and theoretic framework used in discussions of symbolic representation and arithmetic encoding. In this fictive taxonomy, a numaral consists of tokens that encode both magnitude and, in some variants, operational context, allowing compact expressions of numeric information.

Etymology: The term numaral blends Latin numerus with the -al suffix common to classification terms, mirroring terms like decimal or ordinal in style. The term is used primarily in thought experiments and educational discussions about numeral representations.

Notation and structure: A numaral expression is built from a finite set of base tokens and optional operator tokens. Each base token represents a fixed magnitude, while operator tokens specify arithmetic operations. Evaluation follows a defined algorithm that processes tokens from left to right with standard operator precedence.

Examples: In a simple variant, the symbols N3 and N5 denote three and five, and the operator + denotes addition. The expression N3 + N5 evaluates to N8. In other variants, a single token may encode a combined value and operation, enabling extremely compact notation.

Usage and significance: Numaral is used in theoretical discussions to examine how changing the representation of numbers affects cognitive load, learning, and computational models. It is not an established system and there is no consensus on standard notation or evaluation rules. Practical adoption remains limited to hypothetical or pedagogical contexts.
