REVIEW

Can I get the original one from Jamuna Future Park, Bashundhura? Do you have any outlet at Jamuna Future Park?
By Mahbub . July, 2025
It's a non-programmable scientific calculator ideal for students. It supports a lot of features, including complex number calculations, matrix operations, and equation solving. The natural textbook display makes expressions easy to read and enter, just like in textbooks. It's solar-powered with battery backup, ensuring long-term reliability. The build is sturdy, the buttons are responsive, and it's approved for most exams like board exams such as(SSC & HSC). Overall, it's a reliable and versatile tool for advanced math.
