New: A brand-new, unused, unopened and undamaged item in original retail packaging (where packaging . Like I said, I never needed to replace any so as far as I’m concerned, with regular everyday use this battery is super long lasting! conversion factors were not revised at all, which makes them totally unacceptable at the new precision!

The frequently-used shifted functions at the top-left of most keys have been imprinted using an odd yellowish-orange paint that under some lighting conditions is very hard to see. Calculate linear regression, quadratic regression, logarithmic regression, e exponential regression, ab exponential regression, power regression and inverse regression. This allows a key to cant slightly clockwise or counter-clockwise though the panel key hole and cause a ragged uneven presentation.

G This is a very capable product, but in trying to cram so much stuff in a small package the designers came up with a complex, un-intuitive mess. Also, the alpha save function allows you to carry exact answers in further calculations, super handy! Statistics and Linear Regression: This calculator can linear regression, quadratic regression, logarithmic regression, e exponential regression, ab exponential regression, power regression and inverse regression.

Recommended for high school and college students learning Algebra II, Trigonometry, Statistics, Calculus, Engineering, and Physics.

This is one of the few calcs that has a fraction function (see photo - ps: equation in photo is [(12/6)/6]).

I wish that complete calculator state was preserved upon automatic or manual shutdown, but all levels of previous calculation history and results display are lost just like on the old model. FX-115ES PLUS has been designed to be the perfect choice for high school and college students learning General Math, Trigonometry, Statistics, Algebra I and II, Calculus, Engineering, Physics.

I am very happy with this purchase and I highly recommend this calculator to anyone who needs a scientific calculator for school and beyond. Also the display on the Casio if far superior to that of the competition, very readable with no eye strain at all. Simultaneous and polynomial solver helps you compute simultaneous linear equations with 2 or 3 unknowns, quadratic equations and cubic equations.
