Activity 12: Function blocks

Synopsis: This ITP allows you to create up to three function blocks.

Each function block has an input, a function and an output.

You input the initial value by dropping a number card on the first input box. Changing the sign or value of the function determines what appears in the output box.

When more than one function block is selected, the output from one function block becomes the input into the next function block. Input cards 0 to 9 are selected from the numbers at the top of the screen. Cards with larger numbers or decimal numbers are created using the keypad.
