## Hp 15C Limited Edition Scientific Calculator Review

# Hp 15C Limited Edition Review

The HP 15C Limited Edition was released on the 30^{th} Anniversary of Hp-12C edition. The earlier version (HP 15C Scientific Calculator) was introduced in the market in 1982 but it was discontinued in 1989 and the price of that scientific calculator was about $100. The latest version of Hp-15C i.e. HP 15C Limited Edition was released in 2011 and its price was about $180. The Hp-15C Limited Edition is the latest version of HP 15C Scientific Calculator with the modern ARM technology which is powered by 12C hardware. This new version is very practicle for the power users, providing portability and it provides RPN mode which makes the computation easier. This version is more advantageous to engineers as it provides the complex computation operations like complex numbers, matrix operations, integration, differentiation and roots problems. The new version of the HP-15cis better than its original version in many respects i.e. the design of HP 15C Limited Edition is more simple and elegant, it provides more scientific functions, it is portable as it can be placed in the pocket of a shirt and its keyboard keys are less solid and are user friendly.

The Limited Editionis much faster than the original Hp-15C as it provides the answers of the complex problems like integration of polynomial functions and factorial of non-integers in the glimpse of an eye. HP has provided about one hundred times faster operations than the original Hp-15C edition. The palpable response of the keys of the Limited Edition is another big achievement of Hewlett Packard. The re-released version has a detailed manual about using the calculator for the desired calculations, a sleek and attractive collectible box and a CD for the instructions. The display of the Limited Edition is also better than the original one as it provides a wider display range and better contrast. The processor is much faster and the operating system starts up and shuts down instantly. To sum up the whole story, the Limited Edition is better than the original version in all respects. If you want a fast computations, a large display, palpable response of the keys, portability of the calculator, a scientific calculator with all the functions needed for the engineers and scientists then don’t wait prices are rising fast on the Limited edition as the short supply is gobbled up by die hard HP collectors itching for a chance to own the new HP 15C Limited Edition.

## HP 35s Scientific Calculator Review

# HP 35s Scientific Calculator Review

This calculator is classic by many means. It has the look and feel of a serious machine, and the display of a traditional scientific calculator. If you are a loyal HP user, this calculator will feel familiar. The HP 35s Scientific Calculator is a Reverse Polish Notation (RPN) calculator, which means that it doesn’t require the use of brackets to define priorities for evaluation of operators. Some people are long time RPN users and absolutely swear by the method. Some newcomers claim that RPN is very easy to learn and worth the time. Others, yet, prefer to bypass the whole system and go with a more user-friendly and intuitive interface. The RPN mode comes in handy especially in a scientific calculator with fractions like this one in which fractions can be inputted in a variety of ways, as per the user’s choice. The HP 35s calculator is programmable, a huge plus for those who rely on pre-programming to facilitate everyday calculations, or speed up certain test problems. However, only a few programs can be stored since it limits the number of labels and variables to 26.

This scientific calculator with fractions makes it easy to view and perform both regular as well as mixed fractions. It features a fraction button and gives the user the choice to input the fraction using RPN or algebraic mode. Both modes will return the same result, the main difference is in the format of the input. This is more than just a scientific calculator with fractions, it performs advanced mathematics, especially the type required in scientific, medical and engineering professions. Engineers who are already familiar with RPN may consider this calculator a good choice for the NCEES PE and FE exams. Although, it’s not a good choice for everyone because of its interface, it does deliver on the math. Some features are made to facilitate common problems like two-variable equations. Enter and solve two equations with two unknowns simultaneously using the HP Solve application. Enjoy features like numerical integration, and complex number and vector calculations.

Without solar assistance, expect to change the batteries quite often. The physical design of the calculator is attractive to the serious type, and the buttons are ergonomic and feel easy and comfortable to the touch. A hard protective cover comes included with the calculator.

Unlike most recent scientific calculator models that display four lines at a time, the HP 35s only displays two lines. It also doesn’t feature the newly coveted textbook-like display. This is not the most intuitive or user friendly calculator, but it will certainly appease the more traditional user looking for nothing more than pure programming and mathematical power.
