- Answers are case-sensitive; x and X are not the same.
- Do not type commas in numbers; 5,280 is not correct.
- Use the pad button when entering fractions between commas (for example, fractions in a list). This notation can be typed, but not intuitively. See the examples for details.
- Do not enter mixed numbers, for example, 2½. Instead, use decimals or improper fractions.
- When entering scientific notation, always use a lowercase e and an integer exponent, for example, 1.23e-5.
- Unless instructed otherwise, express angles for trigonometric functions in radians.
- Keyboard characters that are not mathematically useful — for example, &, @, and foreign language characters — are intentionally not displayed when typed. To enter Greek characters, use the buttons or keyboard shortcuts for the tool.
- Do not use function notation — for example, f(x) — as these answers can't be graded.
- Do not round your answer unless the questions instructs you to.
