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

Product Information

Fraction calculations include simplifying fractions and roots, recurring decimal display, remainder calculation and integer division with remainder. Over 280 functions, including fractions, statistics, complex number calculations, base arithmetic, linear regression, standard deviation, computer science, and polar-rectangular conversions. My speed tests use a continuous-sum function that closely reproduces function execution performed by a 2500-iteration Savage benchmark. 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. Read more about the condition New: A brand-new, unused, unopened and undamaged item in original retail packaging (where packaging is applicable).

Statistics and Linear Regression: This calculator can linear regression, quadratic regression, logarithmic regression, e exponential regression, ab exponential regression, power regression and inverse regression. Converts between Standard form and a Decimal: This calculator can transform a displayed decimal calculation result to a fraction or mixed number. Also the display on the Casio if far superior to that of the competition, very readable with no eye strain at all. The hard cover creaks against the calculator body when the unit is picked up, indicating a flimsier or more ill-fitted design compared to the old model.Simultaneous and Polynomial Solver: This calculator will solve simultaneous linear equations with two unknowns, simultaneous linear equations with three unknowns, quadratic equations and cubic equations. It seems like it should be possible, even if it would have to throttle its processing speed while running. New: A brand-new, unused, unopened and undamaged item in original retail packaging (where packaging . Multi-replay function allows you to backtrack step-by-step through calculations, where you can edit expressions and recalculate answers. 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.

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. 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. Granted, the batteries last many, many moons, but still it should have been designed more user-convenient.

I think the 115ES (original) is OK, but (seemingly) unlike a lot of people here, I prefer the Sharp 516 (and even the 506). The calculator its a little light weight compared to may recent calculator that i used back on my college days. Casio's * and most advanced scientific calculator features new Natural Textbook Display and improved math functionality. Simultaneous and polynomial solver helps you compute simultaneous linear equations with 2 or 3 unknowns, quadratic equations and cubic equations.

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.

Complex Number Calculations: Your calculator can perform the following: Addition, subtraction, multiplication, division.

but that’s more on you needing more of a calculator than the average person, not the calculator itself! The TI unit needs to be disassembled with a tiny phillips screwdriver and the entire back must be removed. 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 latter will display both the quotient and remainder, but if used in a chain calculation only the quotient is retained. Calculate linear regression, quadratic regression, logarithmic regression, e exponential regression, ab exponential regression, power regression and inverse regression.

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. I bought the Casio fx-115ES last weeks and was immediately impressed with the number of features available on this inexpensive calculator. conversion factors were not revised at all, which makes them totally unacceptable at the new precision! I have had no issues reading this screen both indoors and out (after exams discussing questions) in all kinds of light scenarios.
