You can certainly spend more or less, but this is the sweet spot for both quality and value. Today, the price range for a scientific calculator runs from about $10 to $20. If you find a mistake, you can correct that mistake and solve the equation again without starting over.Įarly scientific calculators were large and bulky – think early cell phones – and cost a lot. It lets you step forward or backward through your calculations to double-check your work. Instead of starting from scratch, just step back through what you did one element at a time to quickly fix the error.Ī replay function on your scientific calculator is like an advanced undo function. Having an undo feature on a scientific calculator is great for those times you accidentally hit a wrong number. Much like a computer, a programmable calculator lets you execute a stored sequence of operations. If you need to solve a complicated equation for several different values, it helps to have a programmable scientific calculator. It can also let you see both the problem and the solution at the same time to allow for greater comprehension of the mathematical concepts involved. Having a multi-line screen on your scientific calculator allows you to see more of what you entered, which can lessen the chance for a mistake. This way, you can solve a wider variety of complex problems without adding any more keys, which keeps the number of buttons on your scientific calculator to a somewhat manageable number. Multi-function keys give you the ability to perform two or three functions with the same key. Having a scientific calculator with a recallable memory can make solving a string of equations with a common part appreciably easier to do. Does the calculator’s layout make sense to you? If you’re going to be tossing your scientific calculator in a backpack or slipping it into your pocket, having a cover, case, or lid to protect the keys and screen can be invaluable.ĭesign is more than just your favorite color, it’s about how comfortably your scientific calculator fits in your hand and how easy it is to find and press the buttons you use most often. However, there are a few key features and functions that are quite handy to have in a scientific calculator. There are hundreds of functions on a scientific calculator, so covering all the possible options would be tedious. If two power sources make you feel more secure, a dual-powered scientific calculator is a good option.īestReviews Features for scientific calculators If your batteries run out, you can still use solar power. Unless you store it in a drawer or use a protective cover, a solar-powered scientific calculator could be your best option.Ĭombining both power sources can give you peace of mind. The cells can charge from natural or artificial light, so your chances of running out of juice are very slim. If a calculator doesn’t have a lot of electrically demanding features such as printing and graphing – which scientific calculators do not have – then solar power is a great way to go. If it happens at an inopportune time, you’re out of luck. The biggest downside to using batteries, besides the environmental concern, is that when your batteries die, you no longer have a functioning calculator. An argument could be made for rechargeable batteries, however. With all the emphasis on renewable energy sources, it’s pretty hard to recommend a device that uses disposable batteries. Today, scientific calculators are either battery-powered, solar-powered, or dual-powered (solar and battery). Unless you have a desktop adding machine, the days of corded calculators are pretty much over. The only difference is its higher-resolution screen, which allows you to see the solution on a graph. A more advanced scientific calculator will have multi-function keys – activated by keys that work like the shift and option keys on your computer – and they will be able to solve boolean (true or false) as well as variable equations.Ī graphing calculator typically has the same problem-solving abilities as a scientific calculator. Even the most basic scientific calculator can handle sines, cosines, tangents, logarithms, and other functions. It might also be able to figure percentages, square roots, or perform other simple calculations as well.Ībout the time you start getting into algebra, a scientific calculator becomes handy. It can add, subtract, multiply, and divide. There are three different types of calculators: basic calculators, scientific calculators, and graphing calculators.Ī basic calculator only performs basic mathematical functions. Scientific calculators, however, are permitted devices. Because of concerns about cheating, using a smartphone app for math calculations is not allowed in most classrooms or when taking standardized tests.
