problems:
  - stem: "Solve for x:  {a}x = {b}"
    vars:
      a: { choices: [2, 3, 4, 5, 6] }
      x_val: [3, 12]
      b: { expr: "a * x_val" }
    answer: "b / a"
    distractors:
      - "b - a"        # subtracted instead of divided
      - "b + a"        # added instead
      - "a * b"        # multiplied instead

  - stem: "What is the area of a rectangle with width {w} and length {l}?"
    vars:
      w: [3, 12]
      l: [4, 15]
    answer: "w * l"
    distractors:
      - "2 * (w + l)"  # perimeter
      - "w + l"        # half-perimeter
      - "w * l + 1"    # off-by-one
