โ๏ธ How It Works
A scientific calculator performs advanced mathematical operations beyond basic arithmetic, including trigonometric functions, logarithms, exponents, roots, and factorial calculations. It follows the standard order of operations (PEMDAS/BODMAS): Parentheses, Exponents, Multiplication/Division, Addition/Subtraction.

โ FAQ
What is the order of operations?
PEMDAS (US) or BODMAS (UK): Parentheses/Brackets first, then Exponents/Orders, then Multiplication and Division (left to right), then Addition and Subtraction (left to right). Example: 2 + 3 ร 4 = 14, not 20.
What is the difference between degrees and radians?
Degrees and radians are two ways to measure angles. A full circle is 360ยฐ or 2ฯ radians. To convert: radians = degrees ร ฯ/180. Scientific calculators can work in either mode โ make sure you're in the right mode for your calculation.
What is a logarithm?
A logarithm answers: 'to what power must I raise the base to get this number?' logโโ(1000) = 3 because 10ยณ = 1000. Natural log (ln) uses base e โ 2.718. Logarithms are used in science, engineering, and finance (compound interest formulas).
What is Euler's number (e)?
Euler's number e โ 2.71828 is a mathematical constant that appears naturally in growth and decay processes. It's the base of the natural logarithm. Compound interest continuously compounded uses e: A = Pe^(rt).
