Q1: Which pocket calculator is best for daily shop use in India?

For retail shops and daily business, the Casio HL-122TV is excellent due to its dedicated Tax (+Tax/-Tax) and Profit Margin calculation keys, along with a durable metal faceplate. For a lower budget, the Casio HL-815 is highly popular as it runs on easy-to-find AA batteries.

Q2: Are pocket calculators allowed in school and board exams in India?

Simple 8-digit or 12-digit basic pocket calculators (non-programmable, non-scientific) are generally allowed in some commercial exams or college boards, but standard school board exams (like CBSE or ICSE) strictly prohibit any electronic calculators. Always check the official syllabus and guidelines of your specific exam board.

The Casio HL-4A is one of the most compact models (8x5 cm), making it highly portable. The HL-820LV is slightly larger with more ergonomic key spacing and an auto power-off function to preserve battery life, making it a favorite for students.

Q4: How long does the battery of a pocket calculator last?

Standard pocket calculators running on dual power (solar + battery) like the Citizen Sld200 can last 3 to 5 years. Models running purely on button cells or AA batteries typically last 1 to 2 years depending on daily usage.
