Teaduskalkulaatorid, often referred to as scientific calculators, are portable electronic devices designed to perform a wide range of mathematical and scientific calculations beyond the basic arithmetic operations found on standard calculators. They are distinguished by their advanced functions, including trigonometry, logarithms, exponents, roots, and statistical analysis.

These calculators typically feature a multi-line display that can show the input and the result simultaneously, often with the ability to scroll through previous calculations. Many scientific calculators support algebraic notation, allowing users to enter expressions in a natural, left-to-right order, similar to how they would be written on paper. This feature enhances usability for complex equations.

The capabilities of scientific calculators vary widely. Some models offer basic scientific functions, while others are highly sophisticated, capable of symbolic manipulation, graphing functions, unit conversions, and even programming. Programmable scientific calculators allow users to store custom routines and formulas, further expanding their functionality for specific academic or professional needs.

Scientific calculators are essential tools in various fields, including mathematics, physics, engineering, chemistry, and computer science. They are widely used by students in secondary education and higher education, as well as by professionals in research and development, data analysis, and technical fields. Their portability and self-contained nature make them a practical alternative to software-based calculators on computers or mobile devices in situations where external devices may not be permitted or practical.
