Example 33 Show that the ∨ : R × R → R given by (a, b) → max {a, b} and the ∧ : R × R → R given by (a, b) → min {a, b} are binary operations. For max ∨ : R × R → R (a, b) → max {a, b} Here, a, b are real numbers & Maximum of 2 real numbers will also be a real number Hence, ∨ is a binary operation. For min ∧: R × R → R (a, b) → min{a, b} Here, a, b are real numbers & minimum of 2 real numbers will also be a real number Hence, ∧ is a binary operation.
