Worked example

Choose from the displayed signs. With two blanks, calculate the parentheses first.

3 + 3 = 6 → +

  1. Read one problem and its conditions before starting. Work without a timer, and keep the key visible where the task requires it.
  2. Try only the listed operations. With two gaps, calculate the parenthesized part first.
  3. (a □ b) □ c · Step 1: + − · □×1 · Step 2: + − × · □×1 · Step 3: + − × · □×2
Check answers after trying

1: + 2: − 3: × 4: − 5: ×, − 6: +, ×

Choose from the displayed signs. With two blanks, calculate the parentheses first.

Why this answer

  1. 1. 3 + 3 = 6 → +
  2. 2. 4 − 3 = 1 → −
  3. 3. 5 × 3 = 15 → ×
  4. 4. 6 − 3 = 3 → −
  5. 5. (7 × 3) − 2 = 19 → ×, −
  6. 6. (8 + 3) × 3 = 33 → +, ×
  7. If an answer differs, return to the first step that differs and explain the choice. Change the answer after checking rather than guessing a new rule.
  8. Try the next step when the current method feels manageable. You may repeat a problem, use a paper marker, or stop and return later.
  9. Original practice activities, not a standardized test or IQ score. Steps describe the task, not an age or ability grade.
