Practice and check
Worked example
Identical symbols have identical values. Use all equations to find the requested symbol.
○ = 4 → 4
- Read one problem and its conditions before starting. Work without a timer, and keep the key visible where the task requires it.
- Assign one value to each symbol and reuse it in every equation, including the final query.
- ○+○=a; ○+□=b · Step 1: 1 equations · Step 2: 2 equations · Step 3: 3 equations
Check answers after trying
1: 4 2: 5 3: 9 4: 10 5: 9 6: 10
Identical symbols have identical values. Use all equations to find the requested symbol.
Why this answer
- 1. ○ = 4 → 4
- 2. ○ = 5 → 5
- 3. ○ = 6; □ = 9 → 9
- 4. ○ = 7; □ = 10 → 10
- 5. ○ = 8; □ = 11; △ = 9 → 9
- 6. ○ = 9; □ = 12; △ = 10 → 10
- 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.
- Try the next step when the current method feels manageable. You may repeat a problem, use a paper marker, or stop and return later.
- Original practice activities, not a standardized test or IQ score. Steps describe the task, not an age or ability grade.
