![]() 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. ![]() Calculate mean, standard deviation, variance, regression analysis and more.Because of concerns about cheating, using a smartphone app for math calculations is not allowed in most classrooms or when taking standardized tests.
