Number String is an application that teaches addition/subtraction and multiplication/division to students.

6 cards are dealt face up. The player tries to combine some or all of the first 5 cards to equal the value of the sixth card. Players may use any combination of addition, subtraction, multiplication and division. Up to 2 pairs of parenthesis may be added if desired. Besides acquiring points, each time an equivalency is completed a "hidden" background picture is displayed.

What's New

Version 1.5.3:
