Question
Dear ZZ

http://en.wikipedia.org/wiki/Factorial

Can we use Factorials for various computations viz Addition, Subtraction,Multiplication,Division and indices ?.

Subtraction = 3! - 2!

Multiplication = 3! * 2!

Division = 3! / 2!

Exponential / Indices = 3! raised to a power of 2!

Other than the above computations, can we use Factorials in Matrices, Determinants, logarithms, Antilogarithms, Coordinate Geometry etc.

Matrices = 2*2 matrix = 3!,2!,5!,6!
Determinants = 3!,2!,5!,6!
Logarithms = log(10!), log(20!) etc
Antilogarithms = Antilog(1!) etc
Coordinate geometry = plot this points in the Graph paper viz
A(3!,2!), B(4!,-5!),C(-7!,-8!),D(6!,-3!)
Trigonometry = Sin(5!), Cos(4!), Tan(2!), Sec(3!), Cosec(6!), Cot(7!)

etc

Thanks & Regards,
Prashant S Akerkar

Addition = 3! + 2! = 8

Subtraction = 3! - 2! = 6

Multiplication = 3! * 2! = 12

Division = 3! / 2! = 3

Exponential / Indices = 3! raised to a power of 2! = 36

You can do  the rest.
