This quiz helps students practice combining like terms. It involves algebraic expression simplification. Using GeoGebra commands such as Random, Join, and Expand, students can generate different algebraic expressions and combine them. Suitable for middle school and above students.

GeoGebra Commands & Parameters

  1. Random(1, 4) → m
  2. Join({{m, m, m, m, m, m, m, m, m}, {1, 2, 3, 4} \ {m}}) → list2
  3. RandomElement(list1) → a
  4. RandomElement(list1) → b
  5. SelectedIndex(levelList) → level
  6. Expand(input) → input2
  7. RandomElement(list2) → n
  8. RandomElement({true, false}) → randomXY
  9. Expand(If[randomXY, f_1(x) + f_2(x), g_1(x, y) + g_2(x, y)]) → ansL1
  10. Random(1, 4) → r
  11. Expand(If[randomXY, h_1(x, y) + h_2(x, y), k_1(x, y) + k_2(x, y)]) → ansL2
  12. If(level ≟ 1, ansL1, ansL2) → ans
  13. If(level ≟ 1, If[randomXY, textQ1a, textQ1b], If[randomXY, textQ2a, textQ2b]) → textQ
