This application (version 2.0) is designed to aid children in learning to add and subtract. Problems on varying levels of difficulty are presented and the child is given two chances to give a correct response. Four levels of difficulty are provided; Easy, Medium, Hard and Very Hard. Using the Macintalk Speech Synthesizer (Apple Computer, Inc.), the computer can speak the problem, answer, and a random phrase indicating whether the correct answer was given or not. Macintalk can be obtained from most bulletin boards or from dealers. If Macintalk is not installed, then chords are played to indicate a correct (high) or incorrect (low) answer.
This program follows the Macintosh interface much better than version 1.0 (my very first program with ZBasic). About Add... allows the shareware information to be displayed. Quit (Command-Q) returns to the Finder. To change levels of difficulty, just click anywhere in the left window to activate it and restart.
Version 2.0 also has the option of selecting 2 or 3 addends. Just pull down the numbers menu and select Two (Command-2) or Three (Command-3) and then the Go button. It can also perform a subtraction test. Pull down the Type menu and select Subtract (Command-S). When subtraction is selected, only 2 numbers are allowed. A window has been added to keep score of the number of answers which were correct, missed once, and missed twice.
This program was developed using ZBasic 5.0 and has been tested on a Macintosh SE with a DayStar Digital accelerator in both 68000 and 68030 modes.
This program is shareware, and as such, no fee shall be charged for its distribution (especially, Budget Bytes and the likes -- EduCorp has permission as of this writing; 14–Jan–1990), nor shall it be offered as an inducement to buy other software or hardware. If you find this software useful and decide to keep it, please send $5.00 to me at
