How to write questions

$ ... $Inline math. Simplify $3 + 4 \times 5$
$$ ... $$Math on its own centered line, good for fractions and long expressions.
\frac{3}{4}Fractions. Also \times \div \le \ge \ne \pi \sqrt{} and x^2.
BackslashesStrict JSON needs every backslash doubled. Leave the box above checked and you can type them singly.
ValuesLeave value out and rows are numbered 100 through 500 automatically.
Daily doublesMark a clue "dailyDouble": true to pin it, or set "dailyDoubles": 2 on a round to scatter them at random. Random ones favor the higher-value rows and spread across categories. Shuffle DD in the top bar moves them without reloading.
"image"A picture for the clue. Use a filename sitting next to this file ("figures/triangle.png"), a full web address, or a pasted data URI.
"svg"A drawing written inline: "svg": "<svg viewBox='0 0 200 120'>...</svg>". Use single quotes inside so you do not have to escape anything. Figures sit on a white card, so black ink shows up fine.
"figure"A drawn number line: {"type":"numberline","min":-5,"max":5,"point":2,"direction":"right","closed":false}. Good for graphing inequalities.
Figures in answersSame three keys with an answer prefix: answerImage, answerSvg, answerFigure.
