The Casio fx-300ES Plus 2nd Edition is a standard tool for secondary education, designed with a slim body and rounded edges for comfortable handling. The chassis is made from high-impact ABS polymer, which provides a sturdy feel for daily household and school use. Tests show it is designed to survive typical desk-height drops of approximately three feet.
This model features a "Natural Textbook Display," which renders fractions and square roots as they appear in printed curriculum. This helps monitor accuracy during data entry. The device utilizes a dual-power path; the solar cell can operate in light as low as 50 lux, which helps extend the life of the internal LR44 battery for several years.
