The work of the landlord has to deal with a lot of data, so basically there are calculators . The company has a larger voice-based desktop calculator, and the car has a Casio calculator at school . Recently I plan to buy a calculator that can be placed in a laptop bag. The requirement is small size, light weight, dual power supply, and finally I bought this powerful 1548A calculator through layer screening . This calculator measures 170*108*15mm, which can be said to be very thin.
