Description & Goals

Summary

The calculate activity provides a generic calculator. The interface provides the simplest functions directly and should therefore be easy to use for the youngest children. However, it does support more complicated math and variables.

Goals

Teach children some math

Collaboration

Basic collaboration is functioning. The history box shows equations entered by buddies in their own color.

Functionality

  • Variables: type 'apples:5' (and tab-completion of variable names)
  • Function plotting: type 'plot(sin(x),x=0..360)'
  • To add Variables
   1)Type the name of the Variable in the Label box. 
   2)Then move to the next line down and Put in the amount of the Variable.  
   3)Push the enter button (On computer Screen)
