5. ART OF MATHEMATICS

E.g. Lambda calculus in mathematic

6. ART OF MATHEMATICS

E.g. Lambda calculus in Scheme

((lambda (a b) (+ a b)) 1 2)

"lambda" as a keyword for introducing a procedure
(Anonymous function).

using lambda expressions not as simple procedure
instantiations but as "control structures and
environment modifiers.
( 1 + 2 = 3)
