Scientific & Basic Calculator
A scientific calculator evaluates advanced arithmetic, trigonometry, exponents, natural logarithms, roots, and factorial operations directly in the browser. Designed with strict mathematical order of operations (PEMDAS), it accurately computes complex formulas such as sin(45°), log(100), and square roots with high floating-point precision.

How Do You Calculate Scientific Calc Step by Step?
Evaluating 25 + (14 × 3) - sqrt(81)Expression: 25 + (14 × 3) - sqrt(81)
Parentheses: 14 × 3 = 42
Square root: sqrt(81) = 9
Arithmetic: 25 + 42 - 9 = 58
Final Solution:58
Scientific Calc Questions and Answers
You can toggle between Degree (DEG) and Radian (RAD) mode at the top of the keypad.
