The Samsung Galaxy S, Droid X, MyTouch 3G Slide, Evo 4, the list goes on and on. Many of the hottest smartphones on the market today run on Google’s Android OS. With each new device released for Android, the buzz about the system grows.
A quick search of “calculator” on the Android Market returned about a thousand results, far than most people would like to sort through. You’ll find dozens of tip calculators, BMI calculators, mortgage calculators, love calculators, and more that are probably not what you are looking for. Luckily for you, we’ve done the hard work of searching through all of those apps for you and found these 6 worthy of your consideration.
#1 – HandyCalc Calculator by mmin
HandyCalc Calculator is our choice for the top calculator available on Android today. This app give you a lot of the basic functionality of a TI-84, including all scientific calculator capabilities, graphing, and the ability to solve systems of equations. Answers can be returned in fraction and radical form or converted to decimals. There are also simple copy and paste capabilities, something that should be available in more apps. The app even comes with a demo doc and a link to a video tutorial. There’s a lot to like here, and even if it’s not perfect, it comes as close as anything we’ve seen.
Pros: Free, scientific and graphing capabilities, solves systems of equations, returns both exact answers for fractions/radicals as well as decimal approximations.
Cons: Missing features of a typical grapher such as max/min, intercepts, etc.; swiping between keypads presses buttons and feels awkward; two different “equals” buttons (which perform different functions) can be a bit confusing.
Cost: FREE
#2 – Scientific Calculator by Kreactive Technologies
Scientific Calculator had the nicest UI of any calculator app we reviewed. Buttons are attractive, with a nice top-lit effect, and a good size, making them easy to press. A flick scroll or double arrow button allows you to easily access scientific functions. The calculator does feature some basic graphing capabilities. This calculator comes very close to 2-line functionality. You can enter an entire calculation before pressing enter. Then you can return to previous calculations by long pressing the input area. There are more powerful apps on this list, but UI is important in an Android app, and Scientific Calculator has a great one.
Pros: Free, attractive UI, some functionality of a 2-line calculator, some graphing functionality
Cons: Graphing functions limited; comments in the market indicate some users confused by lack of +/- button, although we found this easy to work around.
Cost: FREE
#3 – Calculus Tools by Andy Mc
A fantastic calculator app for calculus students is Calculus Tools. As its name implies, this app is focused almost exclusively on calculus, so it’s not for everyone. The app can find integrals as well derivatives up to the fourth degree, both algebraically as well as with with defined limits. It also has the ability to help you solve problems involving arc length, surface area, and Taylor series. Your results can also be graphed. The app also contains a pretty extensive list of formulas that calculus students have to memorize. The only real drawbacks with this app are that its scientific calculator mode is still in beta and fairly limited, and that all inputting must be done with your default keyboard.
Pros: Free, solve calculus functions symbolically or numerically, ability to graph functions, great “cheat sheet” of calculus formulas
Cons: Scientific calculator features still in beta, must use default keyboard instead of a custom math UI
Cost: FREE or $2.50 donate version
UPDATE: A math keyboard was added in an upgrade to Calculus Tools
#4 – Arity Calculator by Mihai Preda
Arity Calculator has a far different UI and capabilities from the other apps on this list. If you are looking for a good 3D grapher, this is it. You have the option to graph in either 2D or 3D, and simply pressing enter will take you to a clear prompt but will save your equation where it can easily be tapped if you need it later. We’d find it hard to recommend this calculator to a novice, but it’s sharp 3D features will definitely appeal to many users. Arity is also an open source app.
Pros: Free, open source, fast, 3D capabilities, screenshots of graphs
Cons: Almost all commands (such as sin, cos, tan) have to be typed out; although you can navigate graphs and zoom in and out, there is no way to trace, find intercepts, etc.
Cost: FREE
#5 – RealCalc Scientific Calc by Brain Overspill
If you’re looking for something comparable to a TI-30 (one line), the RealCalc Scientific Calc fits the bill. It’s free, fast, and offers all the functionality of a standard scientific calculator. It also features an excellent help menu for new users. The UI isn’t exactly the sexiest, but we are sure some will appreciate how much it authentically looks like a retro calculator. Although we’d have preferred to see an authentic two line display, the developer has provided a previous answer feature, which can be set to retrieve numerous previous results.
Pros: Free, fast, simple to use, offers functionality of a standard scientific calculator, Reverse Polish Notation option will appeal to some
Cons: One-line calculator interface, no graphing options, retro UI straight out of 1985 will not be for everyone
Cost: FREE
#6 – Calc+ by EricJohnson
Like many Android apps, Calc+ is available both in free and paid versions. The free version gets you the features you expect in a scientific calculator. The paid version offers the additional functionality of haptic feedback (vibrate) and unit conversions. In a clever UI decision the developer allows users to switch between a simple calculator and scientific mode by rotating rotating from portrait to landscape mode. The design is minimalistic, yet attractive. The biggest drawback to Calc+ is no ability to change from its default mode of radians into degrees.
Pros: Free version available, simple and attractive UI
Cons: One-line interface, trig calculations only in radians
Cost: FREE or $.99

Excel is perhaps the most important computer software program used in the workplace today. That’s why so many workers and prospective employees are required to learn Excel in order to enter or remain in the workplace.
From the viewpoint of the employer, particularly those in the field of information systems, the use of Excel as an end-user computing tool is essential. Not only are many business professionals using Excel to perform everyday functional tasks in the workplace, an increasing number of employers rely on Excel for decision support.
In general, Excel dominates the spreadsheet product industry with a market share estimated at 90 percent. Excel 2007 has the capacity for spreadsheets of up to a million rows by 16,000 columns, enabling the user to import and work with massive amounts of data and achieve faster calculation performance than ever before.
Outside the workplace, Excel is in broad use for everyday problem solving.
Let’s say you have a home office. You can use Excel to calculate sales tax on a purchase, calculate the cost of a trip by car, create a temperature converter, calculate the price of pizza per square inch and do analysis of inputted data. You can track your debt, income and assets, determine your debt to income ratio, calculate your net worth, and use this information to prepare for the process of applying for a mortgage on a new house. The personal uses for Excel are almost as endless as the business uses for this software – and an Excel tutorial delves into the practical uses of the program for personal and business use.
The use of spreadsheets on computers is not new. Spreadsheets, in electronic form, have been in existence since before the introduction of the personal computer. Forerunners to Excel and Lotus 1-2-3 were packages such as VisiCalc, developed and modeled on the accountant’s financial ledger. Since 1987, spreadsheet programs have been impacting the business world. Along the way, computerized spreadsheets have become a pervasive and increasingly effective tool for comparative data analysis throughout the world.
Today, end users employ Excel to create and modify spreadsheets as well as to author web pages with links and complex formatting specifications. They create macros and scripts. While some of these programs are small, one-shot calculations, many are much more critical and affect significant financial decisions and business transactions.
Widely used by businesses, service agencies, volunteer groups, private sector organizations, scientists, students, educators, trainers, researchers, journalists, accountants and others, Microsoft Excel has become a staple of end users and business professionals.
The beauty of Excel is that it can be used as a receiver of workplace or business data, or as a calculator, a decision support tool, a data converter or even a display spreadsheet for information interpretation. Excel can create a chart or graph, operate in conjunction with Mail Merge functions, import data from the Internet, create a concept map and sequentially rank information by importance.
Excel offers new data analysis and visualization tools that assist in analyzing information, spotting trends and accessing information more easily than in the past. Using conditional formatting with rich data display schemes, you can evaluate and illustrate important trends and highlight exceptions with colored gradients, data bars and icons.
Indeed, Excel can be customized to perform such a wide variety of functions that many businesses can’t operate without it. Excel training has become mandatory in many workplaces; in fact, computer software training is a must for any workplace trying to keep up with the times.
Let’s say you’re an employer with 97 workers, 17 of whom called in sick today, and you want to know the percentage represented by absentees. Excel can do that. You can learn Excel and use it to determine the ratio of male to female employees, the percentage of minorities on the payroll, and the ranking of each worker by compensation package amount, including the percentages of that package according to pay and benefits. You can use Excel to keep track of production by department, information that may assist you in future development plans. You can create additional spreadsheets to track data on vendors and customers while maintaining an ongoing inventory of product stock.
Let’s say you want to know your business production versus cost. You don’t have to be a math wiz – you just have to learn Excel. Excel allows you to input all of the data, analyze it, sort it according to your customized format, and display the results with color, shading, backgrounds, icons and other gimmicks that offer time-saving assistance in later locating precisely the information desired. If this spreadsheet is for presentation purposes, Excel helps you put it together in such a visually appealing way that the data may seem to pop and sparkle.
The single most important thing an employer may do is learn Excel – it is one of the most essential tools of the workplace.

Around one hundred and fifty years ago, businesses ran their day to day operations completely different from what businesses of the modern era do to run their day to day operations. People back then worked under candle light doing math calculations on paper, the old fashion way, before electricity came about in the early 20th century. Now, most of the civilized world wouldn’t know what to do with themselves without technology. Imagine not even having a calculator for math or the internet to do research. Yes, I know, it is hard to believe people were able to survive without these advanced tools that we take for granted each day. The advances in communication combined with the evolution of the IT industry has made it possible for people to do business throughout the world in real time. Improvements in IT improve our lifestyles and business by allowing computers to reduce complications and enrich possibilities.
These days, the name “Information Technology” has managed to encompass many aspects of computer technologies invented in the past couple decades. These IT spectrums can be covered in many types of professional fields such as Management Information Systems, Computer Networking, and Software Design. Our ancestors couldn’t even fathom what our society has accomplished.
In medicine, Information Technology also plays a substantial roll. Doctors take pictures with machines like a computerized axial tomography (CAT) or magnetic resonance imaging (MRI) and can print out three dimensional images of bones, muscles, and organs. These images can help map out patient’s problems and help save lives. This day and age, it is difficult to find a field or industry that IT has not been greatly affected.
IT is completely responsible for how organized our civilization has become. The corporate world was only made possible by the communication information technology has put in place between both computer software and hardware. From a personal stand point, it would be difficult for most people to name a single person doesn’t use the internet on a regular basis.
With the increasing new technologies coming out everyday, employees in the Information Technology work force must constantly re-educate themselves with all the new technologies. This makes IT a very demanding field as it is always developing and perfecting. The process of improvement is what makes this such a desirable aspect to almost any business. It is very important for anyone in the IT field to always stay up to date with all newly developing technologies that relate to their industry. IT is now the complete backbone to almost any business and its ability to be competitive and efficient.
