Field notes

The calculator models exam-relevant details rather than only basic arithmetic. Its guide covers the eight-digit entry limit, memory indicators, error recovery, and percentage behavior under different pending operators; examples include 100 + 20 + 10% = 132 and 8 ÷ 2 × 2 = 8. Keyboard input is optional, while the page warns that the cited 2020 test-day instructions required mouse input.
