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

Product Information

My speed tests use a continuous-sum function that closely reproduces function execution performed by a 2500-iteration Savage benchmark. With 460 total functions, this calculator is ideal for students in general math, pre-algebra, algebra I and II, geometry, trigonometry, statistics, calculus, chemistry and engineering. Recommended for high school and college students learning Algebra II, Trigonometry, Statistics, Calculus, Engineering, and Physics. I bought the Casio fx-115ES last weeks and was immediately impressed with the number of features available on this inexpensive calculator.

You can change your choices at any time by visiting Cookie preferences, as described in the Cookie notice. Also the display on the Casio if far superior to that of the competition, very readable with no eye strain at all.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. There is no a piece of rubber on the back of the calculator to stop it from sliding all over the table.

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. Over 280 functions, including fractions, statistics, complex number calculations, base arithmetic, linear regression, standard deviation, computer science, and polar-rectangular conversions.The label for the constant and conversion factor table is applied canted slightly on the inside of the hard cover. 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!

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! Complex number calculations include addition, subtraction, multiplication, division, augment and absolute value, reciprocal, square and cube and conjugate complex numbers. Whether you are an experienced DIY-er or a first time battery replacer, this guide is designed to help you get your Casio FX115ES PLUS calculator back up and running in no time. I think the big difference to me is that the Sharps have more commands available on the keyboard, which makes it a faster general use calculator.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. 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.

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. The TI unit needs to be disassembled with a tiny phillips screwdriver and the entire back must be removed.Converts between Standard form and a Decimal: This calculator can transform a displayed decimal calculation result to a fraction or mixed number. Simultaneous and polynomial solver helps you compute simultaneous linear equations with 2 or 3 unknowns, quadratic equations and cubic equations.
