1. Intervals and Inequalities

When describing a range of numbers, the computer needs to know if the endpoints are included or excluded.

  • Interval Notation: Use your keyboard to type (, ), [, and ].

  • The Union Symbol (∪): Type a capital U to join two intervals together (e.g., (a,b] U (x,y)).

  • Inequalities: You don't need a special keyboard for ≥ or ≤. Type <= for "less than or equal to" or >= for "greater than or equal to".

2. Matrices (The Comma and Enter Method)

You do not need to find a special bracket tool to build a matrix; the system builds it as you type.

  1. Start your first row: Type your numbers separated by commas (e.g., 1, 2).

  2. Create a new row: Press Enter on your keyboard.

  3. Finish: The computer will automatically wrap your numbers in large matrix brackets.

3. Lists and Sets

If a question asks for multiple answers (like the two roots of a quadratic equation), you must separate them properly.

  • Use Commas: Put a comma between each item in your list.

  • Example: If the answers are a, b and c, type a, b, c.

4. Geometry and Graphs

For interactive problems, your mouse or touch screen becomes your primary tool.

  • Coordinate Points: Always format as (x, y) with parentheses and a comma.

  • Moving Objects: Click and drag points on a graph or number line to change their position.

  • Navigating Graphs: Hold the Shift key while scrolling to zoom in, or hold Shift while clicking and dragging to pan across the graph.
