Views

• The top tool bar has several buttons.
• The other area can be split into 2 even views. The top view is for questions. The bottom view is for the answers or the analysis.
• The rules are always shown in the full screen.
• For small devices, when you touch the answer area, it will expand to the full screen. After you choose one answer, it will shrink back to the bottom half of the screen.

Swipe up and down

• The dot line between the question and the analysis can be swiped up. When the analysis is in the full screen, the top line can be swiped down.
• The content in the question area can be swiped up and down if it is longer than half of the screen.
• The content in the analysis area can be swiped up and down if it is longer than the analysis area.
• The rules can be swiped up and down if it is longer than the screen.

Rules

Some rules are available. Each rule is explained with examples. A different example will be generated each time you access the rules.

Answer is locked

After you view the solution or the analysis of the question, you will not be able to change the answer any more.

 

Text size

You can choose the size that is good for you. When one question has a wider or higher formula, the text size will be adjusted to display this formula. When you change the orientation or the analysis area between the half and full screen, the text size will be adjusted automatically.

When you are in the menu to choose the text size, both the current text size and the chosen size will be ended with less than marks "<". If you only see one "<", the question is displayed with your chosen size.

Graph block

A warning of “>> Graph block too large <<” is shown if the height or the width of the view is not enough to display the graph block. You can adjust the height or the width in the following ways.

• Change to landscape to get larger width.
• Change to the full screen for the analysis to get larger height.
• Making the text size smaller will make the graph block smaller.

Set 100

This functionality is available when you subscribe to the application. It will hold the last 100 questions you studied recently.

In the Set100 mode, you cannot change the orientation and text size. When you need to adjust your graph block, you can exit the Set100 mode and go back to the same question easily.

• Go to the question that requires changes.
• Press the Done button to exit the Set100 mode.
• Press the Setup button to change the orientation and/or the text size.
• Press the Question button and choose the Set 100 option. Choosing the third option (last run) will bring you back to the last question before you exited the Set100 mode.

Background colors of answers



• The color of all backgrounds is blue if no answer is selected yet.
• The selected answer has a red background.
• If the answer you selected is correct, after you leave this question and come back to this question, the color of its background will be changed to green. From then on, you cannot change the answer of this question any more.
• After you view the solution, the background color of the correct answer will be changed to green. From then on, you cannot change the answer of this question any more.

Category

This functionality is available for Trove Math 3 when you subscribe to the application. This is one option for Set 100. You can select one of "Exponent", "Logarithm", "Function", "Sequence", and "Mixed" to generate the new questions for "Exponent", "Logarithm", "Function", "Sequence", or "all of Exponent, Logarithm, Function, and Sequence". It will always generate the new questions for all of Exponent, Logarithm, Function, and Sequence without the subscription.

When you are in the category menu, the current category is ended with a less than mark "<".

The next section describes Magic 12. If you can access Set 100, you subscribe to the application and Magic 12 is not available to you.

Magic 12

When your subscription has ended, the app will count the numbers of correct answers, incorrect answers, and unanswered questions. If you work hard, you will still be able to see the solutions and the analysis.

When the following “magic” formula is satisfied,

the number of correct answers – (the number of incorrect answers + the number of skip questions) >= 12

you will be able to study the solutions and the analysis without the subscription.

When you subscribe to the application, there are only 2 options (“Next question” and “Set 100”) for you to choose after you press the Question button. If your subscription has ended, a third option shows the number of correct answers you need to make to satisfy the magic formula. When you see “Great job!” you will be able to study the solutions and the analysis without the subscription. Press this option to view your counts of correct, incorrect, and unanswered questions.

Click sound

One of the Setup options allows you to turn on or off the click sound.
