2. The branch of mathematical logic concerned with the relationship between logically equivalent statements and expressions
Equivalence logic allows us to prove that two different formulas are logically equivalent.

3. In computer science and programming, the logical operations that determine when two values or expressions are functionally identical
The equivalence logic operator checks if both conditions produce the same result.
O operador de lógica de equivalência verifica se ambas as condições produzem o mesmo resultado.
Equivalence logic is primarily a technical term used in academic and professional settings in both English-speaking countries and Brazil. It is fundamental to computer science education and digital logic design. The concept is taught universally in mathematics and logic courses, with the same terminology across different Portuguese-speaking regions.
