Linear Notation

A system for representing mathematical expressions in a single line of text, as opposed to the conventional two-dimensional spatial layout used in print mathematics. In standard mathematical notation, spatial arrangement carries meaning — fractions stack numerators above denominators, exponents are raised, and radical symbols extend over their contents. Linear notation replaces these spatial relationships with explicit delimiters, operators, and structural markers that can be read sequentially. Linear notations are essential for making mathematics accessible through braille (which is inherently one-dimensional) and speech (which is sequential). Examples include Lambda Code, LaTeX input syntax, and various computer algebra system formats.
