Visual F# 100 Examples: Example Number 7

So far I have been sharing to you guys some examples of Window Based application in Visual F#. This time, for variation sake lets make some console application:

Problem: Make a simple console application mind reader game.

Visual F# 100 Examples: Example Number 6

Problem. Create an application that will display the surface area of a cube. The surface area of a cube can be computed by multiplying the inputted side by itself and multiplying the product by 6.
