Casio FX-115ESPLUS calculator - calculators (Pocket, Battery/Solar, Scientific calculator, Purple, Silver, Plastic)

Product Information

Statistics and Linear Regression: This calculator can linear regression, quadratic regression, logarithmic regression, e exponential regression, ab exponential regression, power regression and inverse regression. but that’s more on you needing more of a calculator than the average person, not the calculator itself! There is no a piece of rubber on the back of the calculator to stop it from sliding all over the table. Granted, the batteries last many, many moons, but still it should have been designed more user-convenient.

To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. I am very happy with this purchase and I highly recommend this calculator to anyone who needs a scientific calculator for school and beyond. Over 280 functions, including fractions, statistics, complex number calculations, base arithmetic, linear regression, standard deviation, computer science, and polar-rectangular conversions. This allows a key to cant slightly clockwise or counter-clockwise though the panel key hole and cause a ragged uneven presentation. Available items may ship directly from the manufacturer and cannot ship next day, 2nd day or 3rd day.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. Also, the alpha save function allows you to carry exact answers in further calculations, super handy!

And probably as consecuence of the second drawback, in my case, it does not rest on 4 points (just in 3 points) so while pushing buttons on the calculator makes the calculator go up and down making loud "clack-clack" noises which annoy me. If the item comes direct from a manufacturer, it may be delivered in non-retail packaging, such as a plain or unprinted box or plastic bag.

The label for the constant and conversion factor table is applied canted slightly on the inside of the hard cover. I bought the Casio fx-115ES last weeks and was immediately impressed with the number of features available on this inexpensive calculator. 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. In this guide, we will walk you through each step of the process, providing detailed instructions and helpful tips to ensure a successful battery replacement.Matrix mode allows you to perform matrix operations on matrices with up to 3 rows and 3 columns, enter vectors and perform vector calculations.

Fraction calculations include simplifying fractions and roots, recurring decimal display, remainder calculation and integer division with remainder.In MathIO entry mode, there is no keyboard buffering, so when entering a long formula, the calculator redraws after each key press, but as the formula becomes longer and slower redraw, it can miss keystrokes. 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! Read more about the condition New: A brand-new, unused, unopened and undamaged item in original retail packaging (where packaging is applicable). The Casio for instance has a small battery compartment in the back which facilitates easy removal/replacement of the single LR44 cell.

Multi-replay function allows you to backtrack step-by-step through calculations, where you can edit expressions and recalculate answers.They were super long lasting, the only time I needed to replace them was when I misplaced them or a friend I loaned it to lost it! The TI unit needs to be disassembled with a tiny phillips screwdriver and the entire back must be removed. conversion factors were not revised at all, which makes them totally unacceptable at the new precision!
