It's amazing that this calculator can break. I am an accountant student in college and despite modern technologies and the rather powerful functionality of modern smartphones, I like to use just such a calculator for financial calculations.
Great guide, thanks! The spudger was necessary for me to separate the case, as I couldn’t separate it with my fingers alone.
使用2.5mm的螺丝刀更好，2mm可能会打滑
