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

Product Information

Over 280 functions, including fractions, statistics, complex number calculations, base arithmetic, linear regression, standard deviation, computer science, and polar-rectangular conversions. This is one of the few calcs that has a fraction function (see photo - ps: equation in photo is [(12/6)/6]). Matrix and Vector Calculations: The Matrix mode allows you to perform matrix operations on matrices with up to 3 rows and 3 columns. The label for the constant and conversion factor table is applied canted slightly on the inside of the hard cover.

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. International products have separate terms, are sold from abroad and may differ from local products, including fit, age ratings, and language of product, labeling or instructions. The fx-115ES Plus 2 is an advanced scientific calculator featuring Natural Textbook Display™ that is an excellent choice for high school and college students learning Algebra II, Trigonometry, Statistics, Calculus, Engineering, and Physics. The fx-115ES Plus manual seems a little better than that of the older model because it is actually a booklet and not a large fold-out sheet.

I bought the Casio fx-115ES last weeks and was immediately impressed with the number of features available on this inexpensive calculator.Granted, the batteries last many, many moons, but still it should have been designed more user-convenient. 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! Most purchases from business sellers are protected by the Consumer Contract Regulations 2013 which give you the right to cancel the purchase within 14 days after the day you receive the item. New: A brand-new, unused, unopened and undamaged item in original retail packaging (where packaging . Converts between Standard form and a Decimal: This calculator can transform a displayed decimal calculation result to a fraction or mixed number.

My speed tests use a continuous-sum function that closely reproduces function execution performed by a 2500-iteration Savage benchmark. The latter will display both the quotient and remainder, but if used in a chain calculation only the quotient is retained. Over time, the battery in your calculator may start to wear down and lose its ability to hold a charge, which can result in your calculator not functioning properly. To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. You can change your choices at any time by visiting Cookie preferences, as described in the Cookie notice.

Simultaneous and polynomial solver helps you compute simultaneous linear equations with 2 or 3 unknowns, quadratic equations and cubic equations. I think the 115ES (original) is OK, but (seemingly) unlike a lot of people here, I prefer the Sharp 516 (and even the 506). 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.

Matrix mode allows you to perform matrix operations on matrices with up to 3 rows and 3 columns, enter vectors and perform vector calculations. Complex Number Calculations: Your calculator can perform the following: Addition, subtraction, multiplication, division. Also the display on the Casio if far superior to that of the competition, very readable with no eye strain at all. Casio's * and most advanced scientific calculator features new Natural Textbook Display and improved math functionality. 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.The Casio for instance has a small battery compartment in the back which facilitates easy removal/replacement of the single LR44 cell. Fraction calculations include simplifying fractions and roots, recurring decimal display, remainder calculation and integer division with remainder. Multi-replay function allows you to backtrack step-by-step through calculations, where you can edit expressions and recalculate answers.
