Sets

The applets are started by clicking the red buttons.


 
The Definition of sets by means of properties of their elements often seems cryptic for beginners, thus making people feel uneasy with the symbolic mathematical language. In this applet the understanding of simple definitions of the form x  N | property } (where N denotes the set of natural numbers) may be checked. It provides some exercise in translating such definitions into everyday language. The applet is started from the red button in its own window.
