It provides standard scientific calculator functions suitable for math, science, and engineering tasks, including essential trigonometric, logarithmic, and power/root operations via dedicated function keys.

Deli describes it as ideal for exams due to its compact form and reliable performance; however, you should always verify with your specific exam guidelines before using it.

Power it on, enter numbers with the numeric keypad, perform operations using the standard arithmetic keys (+, −, ×, ÷), access scientific functions with the dedicated keys, and clear results with the clear/CE key. It’s designed for straightforward, everyday calculations.

Keep it dry and clean with a soft, dry cloth. Store it in a protective case when not in use and avoid exposing it to extreme heat or moisture. Handle the keys gently to prolong life.
