- BRAINLIEST -✨ - Let Ψ be a binary operation defined by aΨb = ab/2. Find the identity element.

Identity element of Binary OperationsAddition. + : R × R → R. e is called identity of * if. a * e = e * a = a. i.e. ...Multiplication. e is the identity of * if. a * e = e * a = a. i.e. a × e = e × a = a. This is possible if e = 1. ...Subtraction. e is the identity of * if. a * e = e * a = a. i.e. a – e = e – a = a.
