Casio fx-115ESPLUS2 2nd Edition, Advanced Scientific Calculator

The Casio FX115ESPLS2S is a scientific calculator designed for students, engineers, and anyone who needs reliable help with college level math and science. It delivers the power to solve algebra, calculus, statistics, and engineering problems while keeping the interface clear and approachable.

A natural textbook style display presents fractions, roots, and integrals exactly as they appear in lecture notes, which makes it easier to spot errors at a glance. The screen shows up to four lines at once, and a multi replay function lets you scroll back through previous steps, edit entries, and quickly verify your work without starting over.

Inside, more than 250 built in functions cover everything from complex numbers to matrices and vectors. You can store up to nine variables, call on 40 scientific constants, and use 40 metric conversions. Differential and integral calculations, as well as base-n operations for computer science courses, are handled smoothly, giving you the flexibility to move between subjects without changing tools.

Dual power keeps the calculator ready in class, the lab, or the field. Solar cells handle everyday light while a battery backup steps in when conditions are dim, and an automatic shutoff preserves energy during downtime. A hard slide case protects the keypad and screen inside a backpack or desk drawer, so the calculator stays ready for the next assignment or exam.
