Is it allowed on the SAT and ACT?

It is on the approved list for the SAT, ACT and many AP exams because it is non-programmable. Confirm against your exam's current calculator policy before test day.

How is it different from the FX-115ES Plus first edition?

The 2nd Edition adds auto power-off and a slightly revised key layout while keeping the same natural display and function set. Both cover the same coursework.

Does it need batteries?

It runs on solar power and uses an LR44 battery as backup in low light. The battery lasts years under normal use.

Can it do integrals and derivatives?

Yes. It computes numerical integrals and derivatives, plus sigma notation, matrices and vectors, which covers most calculus and linear algebra coursework.

What comes in the box?

The calculator and a slide-on hard cover. The battery is already installed.

How does it compare with the TI-36X Pro?

The Casio is easier for fraction and mixed-number entry and has a clearer natural display. The TI-36X Pro adds an equation solver and more constants, so pick based on which your course uses.

Our take on the Casio FX-115ESPLS2-S Scientific Calculator (2nd Edition)

The Casio FX-115ES Plus 2nd Edition is a non-programmable scientific calculator built for high school and college math, science and engineering courses. It handles calculus-style work such as derivatives, integrals and sigma notation, plus fractions, complex numbers, matrices, vectors and unit conversions, on a two-line natural textbook display that shows expressions as written. It runs on a solar panel with an LR44 battery backup, so it keeps working in dim exam rooms. Against the TI-36X Pro it is the friendlier choice for fraction and mixed-number entry, while the TI wins on equation solving and constants; both are allowed on many standardized tests, but check your exam's approved list first.
