Answer first: what is the Calculator input order?
✅ Enter the equation result first. Wait for the panel to accept it, then read the new LED and combine its color with the original result’s odd-or-even state to get the final digit. Do not use the LED lookup before the first input advances the panel.

Calculator answer
Calculate and enter the raw result first. After the panel advances, combine the new LED with the original parity to find the final digit.
Read back: expression → result → LED state.
➗ Two-stage cue: 🔢 calculate and enter the raw result → wait for acceptance → 💡 read the new LED → use the original odd/even state → ✅ press the returned digit.
Capture the expression, operator order, and the confirmation control. Read the expression left to right, calculate the raw result, and enter it first. The LED is a second-stage clue: do not wait for it before entering the arithmetic result, and do not classify the final digit instead of the original result.
What is the exact input order?
- Read the complete expression.
- Calculate the raw result.
- Enter the raw result on the live keypad.
- Wait until the game accepts it and the panel advances.
- Read the new LED and keep the original result’s odd/even state.
- Use the LED table to find the final digit.
- Press the printed final digit wherever it appears on the live keypad.
The raw result and final digit are two separate inputs. A successful first entry is the signal to move to the LED lookup stage.
How should the input be checked?
The interpreter says the expected value and the condition that makes it valid. The input player enters it once, confirms, and reports whether the display advances or shows an error.
How should a calculator solve be checked?
For example, 57 - 17 = 40 and 60 + 17 = 77 still follow the same workflow: read the expression, say the raw result aloud, wait for the indicator-light state, and only then confirm the entry. Two independently documented runs give useful checks: 60 + 22 = 82 with a blue LED and an even result leads to 1, while 37 with a blue LED and an odd result leads to 0. Both outcomes match the corresponding cells in the reference table. These are worked examples, not a substitute for recording the full live state when the game presents a different expression.
When recording a calculator solve, preserve the complete expression, the displayed result, the light color, and the confirmation timing. A result without its indicator state is incomplete because the light is part of the decision.
Final-key lookup
After the raw result is accepted, classify it as odd or even and use the new LED state. The current reference table is:
| Active LED | Odd raw result | Even raw result |
|---|---|---|
| Red | 3 | 5 |
| Green | 2 | 9 |
| Blue | 0 | 1 |
| Yellow | 7 | 0 |
The table agrees with the worked examples: 60 + 22 = 82 with a blue LED and an even result leads to 1, while 37 with a blue LED and an odd result leads to 0. The page tool keeps the two stages separate: it calculates the raw result first, then enables the final-key lookup. If the game has not accepted the raw result yet, do not use the second-stage key.
What should be checked before calculating?
Use this four-field checklist: first number, operator, second number, and LED state. Read the expression twice if a digit is partially hidden or the panel is moving. The operator should confirm whether the panel expects the equation first and the LED-related value second before entering anything.
| Check | Example | Why it matters |
|---|---|---|
| Expression | 57 - 17 | A single digit changes the result |
| Result | 40 | The raw result is the first value to confirm |
| LED | Color and current state | It changes the follow-up mapping |
| Confirmation | Accepted / reset / error | Determines whether to continue or reread |
How should a failed calculator input be recovered?
Stop pressing, record the exact expression and LED state, and check whether the panel reset. Do not reuse the previous result after the indicator changes. Reopen the Module Solver for arithmetic, use Level Lookup to plan calculator practice, and open the puzzle index if the panel is not the calculator module.
