A scientific calculator handles more than basic arithmetic — square roots, logarithms, natural logs, and exponents are everyday tools in algebra, physics, engineering, and finance. Typing these into a phone's default calculator app is often clunky or unsupported. The Scientific Calculator lets you type a full expression like sqrt(16) + 2^3 and get an instant, accurate answer. It's built for students tackling algebra and calculus homework, engineers running quick calculations, and anyone who needs more than a basic four-function calculator.
Functions and exponents (sqrt, log, ln, ^) resolve first, then remaining operators evaluate left-to-right
sqrt(16) + 2^3 = 4 + 8 = 12.

Solution: Make sure you've typed something into the expression field before clicking Calculate.
Solution: Remember that functions and exponents resolve first, then remaining operators evaluate strictly left-to-right — use parentheses to control the order explicitly.
Solution: Logarithms are undefined for negative numbers and zero — enter a positive value inside log() or ln().
Solution: Make sure each function has matching parentheses, e.g. sqrt(16) + log(100), not sqrt(16 + log(100).
Functions and exponents resolve first; the remaining + − × ÷ operators evaluate strictly left-to-right — use parentheses around functions to control grouping.
sqrt, log (base 10), ln (base e), and ^ for exponentiation, plus the four basic operators.
Yes, expressions are evaluated locally in your browser and nothing is sent to a server.
Yes, negative numbers are supported inside functions and as standalone operands.
Yes, the calculator is fully responsive and works well on phones and tablets.
Yes, you can chain sqrt, log, ln, and exponents together, such as sqrt(16) + log(100).
No hard limit — you can enter as long an expression as needed, as long as the syntax is valid.
