I brought this calculator for my maths and physics graduation papers. It's been very slightly used (only during 2-3 exams). It's perfectly in working condition. Also it is dual powered, it works on solar energy as well as battery and thus, you can just keep it in some outdoor areas and can use it without worrying about the battery back up. I am selling it here coz I won't need it any longer.Hope you like the product.
Keep on calculating✌️.
