How to use it
Use it to verify results, chain operations and reuse one value via memory. Decimals, history and clear (C/AC) are built in.
Order of operations is applied automatically: parentheses first, then multiplication and division before addition and subtraction.
- Operations: +, −, ×, ÷.
- Decimals: use a period for precise results.
- Keyboard: digits, operators, Enter for "=", Escape to clear.
Memory, history and clear
Memory holds one intermediate result between calculations.
- M+ adds the display to memory, M− subtracts.
- MR recalls the stored value, MC clears it.
- C clears the input, AC clears all.
History shows your steps and helps find errors.
Sample calculations
Add: 15 + 27 = 42.
Multiply: 6 × 9 = 54.
Divide: 200 ÷ 8 = 25.
Decimals: 4.1 + 3.9 = 8.
Order: 5 + 2 × 6 = 17; (5 + 2) × 6 = 42.
