Number Line: Add/Subtract Game 1.4

This is a straightforward number line activity designed to enhance skills in adding and subtracting positive and negative numbers. Users can select their answers by tapping directly on the number line to match the displayed equation.

The visual aid of the number line facilitates understanding of the solution process. Participants can choose to tap on the answer directly or begin at the starting number, then drag a selector along the line in the appropriate direction and distance to reach the correct answer. Additionally, the device can provide haptic feedback to assist users as they navigate along the line.

The application tracks various metrics, including the number of equations solved by type—such as addition of positive numbers, addition of negative numbers, subtraction of positive numbers, and subtraction of negative numbers—and records how many are answered correctly on the first attempt. This data enables users to compare their performance with friends or classmates.

For users who find subtraction involving negative numbers challenging, a preferences setting allows for negative numbers to be displayed within parentheses, thereby clarifying the equations.

The app also offers customization options, enabling users to select specific types of equations or to allow the app to generate a random mix of addition and subtraction problems involving positive and negative numbers.
