👉 Marked math is a notational system used primarily in mathematical logic and proof theory, designed to enhance readability and reduce ambiguity when writing formal proofs. Unlike traditional mathematical notation, which can be dense with symbols and abbreviations, marked math uses color-coded or highlighted notation to distinguish between different types of logical connectives, quantifiers, and other elements. For example, a statement involving an existential quantifier might be written with a different color to immediately signal its presence, making the structure and flow of a proof clearer. This visual distinction aids mathematicians and logicians in quickly understanding the logical relationships and steps involved in a proof, thus facilitating more efficient communication and verification of mathematical arguments.
