Sharp EL-531THBGR Scientific Calculator - Black/Green

The SHARP EL-531THBGR scientific calculator (green/black) is designed for school-level mathematics and science. It handles 10-digit calculations and features a two-line LCD that displays both expressions and results. The calculator uses symbolic fraction notation, allowing values to appear as fractions rather than decimal approximations, which helps students track equations during algebra or trigonometry. It is operated via a 48-button keypad.

The device is housed in a green and black plastic casing. It does not include a protective cover, leaving the display and keys exposed. It is powered by a single AAA battery, which is not included. An automatic power-off function saves energy by shutting the device down after a period of inactivity. The screen is fixed, maintaining a 15 mm profile. Specialized keys include a negation button for entering negative numbers and a random integer generator for probability exercises.

• Maximum capacity of 9 pending operations – handles multi-stage math problems without clearing the memory.
• Numeric keypad – provides a dedicated section for rapid numerical input.
• Continuous number display – presents figures without digit separators for direct reading.
• Non-backlit LCD – maintains visibility in standard lighting without excessive battery drain.
• 115g weight – a lightweight build that adds minimal bulk to bags or pockets.
• 80 x 161 mm dimensions – a compact footprint suitable for storage in small cases.
