Entering Your Answers in Derivita — Basics

Master the Workspace: Using the Toolbar, Preview Window, and Real-Time Feedback to Avoid Common Typing Errors

Digital math can be picky. Sometimes you have the right answer on your paper, but the computer marks it wrong because of how it was typed. Use these tools to make sure your work is read correctly every time.

Entering an answer in Derivita works much like using a calculator, but you can do everything with the keys on a standard keyboard.

1. The Math Toolbar

The toolbar is smart: it stays hidden to save space and only appears when you click in the answer box.

  • Buttons vs. Keys: You can click the icons (like the fraction ½ or square root √a) or use your keyboard shortcuts. For example, typing / instantly creates a fraction bar.

  • Special Symbols: Use the toolbar to find symbols that aren't on a standard keyboard, such as π, ∞, and √a.

2. The Preview Window (Your Final Check)

As you type in the box labeled "Answer," a preview window appears on the right. This shows exactly how Derivita is interpreting your math.

  • Watch the Formatting: Derivita follows a strict "order of operations." If you type 1/x+2, the computer thinks you only want the x in the fraction.

  • Use Parentheses to Group: To put multiple terms under a fraction bar or inside an exponent, wrap them in parentheses 1/(x+2).

3. Fixing "Invalid Input"

If the preview window shows Invalid Input, it just means the system doesn't understand what you've entered yet.

Quick Fixes:

  • Incomplete Parentheses: Make sure every ( has a matching ).

  • Comma Errors: Do not use commas in large numbers (type 10000, not 10,000). Commas are only for separating different answers in a list.

  • Incomplete Symbols: If you use a square root or exponent, you must type a value inside the box.

  • You're not done typing: For example, if you're entering 1+2=3, the computer won't understand 1+2=, because the equal sign needs to have something on both sides.

4. Exact Answers vs Rounded Answers

Most questions require an exact answer, so only round when the instructions specifically tell you to.

  • Correct (Exact): Type 1.4081

  • Incorrect (Rounded): Typing 0.33 or 1.41 will likely be marked wrong unless the instructions specifically ask you to round.

  • Simplifying: Most of the time, 2/4 and 1/2 are both accepted unless the instructions say "Give your answer as a simplified fraction."

When a problem tells you to round, wait until you’re ready to enter your final answer. If you round while you’re still working, your final result may end up slightly incorrect.
