Using the calculator
Use it to double-check answers, chain sums and store one value in memory. Decimals, a history list and clear (C/AC) are included.
BODMAS applies automatically: brackets first, then × and ÷ before + and −.
- Operations: +, −, ×, ÷.
- Decimals: use a full stop as the decimal point.
- Keyboard: number keys, operator keys, Enter for equals, Escape to clear.
Memory and history
One value can be stored in memory between sums.
- M+ adds the display to memory; M− subtracts from it.
- MR recalls the stored value; MC clears memory.
- C clears the current input; AC clears everything.
History lists your recent sums so you can spot mistakes.
Example calculations
Addition: 18 + 33 = 51.
Multiplication: 7 × 8 = 56.
Division: 144 ÷ 12 = 12.
Decimals: 2.5 + 2.5 = 5.
Order: 3 + 4 × 5 = 23; (3 + 4) × 5 = 35.
Typical uses
- Double-checking homework or receipts.
- Unit conversions and simple ratios.
- Reviewing past sums in the history list.
