The ≔ (colon equals) symbol is a mathematical operator commonly used to denote assignment or mathematical definition. In math and logic, it explicitly indicates that the term on the left is being defined by the expression on the right, distinguishing it from a standard statement of equality. While primarily found in academic papers and formal documentation, it occasionally appears in technical discussions to clarify when a new variable is being declared.
