GeoGebra 命令及参数

1. Random(2, 12) → b
2. Random(1, 2) → format
3. If(b > 3, {"" + (c + floor(b / 2)) + "", "" + (c + ceil(a / 2)) + "", "" + (c - floor(b / 2)) + "", (("" * c) * "")}, {"" + (c - 1) + "", "" + (c - 2) + "", "" + (c + 1) + "", "" + c + ""}) → labelnums
4. Shuffle(labelnums) → l1, {"5", "6", "7", "4"}
5. IndexOf("" + c + "", l1) → d
6. LaTeX(problemscorrect, true, true) → text4
7. LaTeX(numberofproblems, true, true) → text3
