Scientific Calculator
A full scientific calculator that evaluates a whole expression at once rather than one button press at a time. Type something like sin(30) + sqrt(16) * 2 or log(1000) + pi, and it computes the result respecting the correct order of operations and parentheses. It supports the common scientific functions including sine, cosine and tangent (in degrees), natural and base-ten logarithms, exponents, roots, factorials and the constants pi and e. Because you can see and edit the full expression before evaluating, it is easier to catch mistakes than with a traditional button-by-button calculator. The parser is self-contained and safe, running entirely in your browser with no external libraries. Type your expression and press evaluate to get an instant answer.
How to use Scientific Calculator
- Type a math expression using numbers and functions.
- Add parentheses to group operations as needed.
- Press equals to evaluate.
- Read the computed result.
Frequently asked questions
What functions does it support?
It evaluates expressions with trigonometry, logarithms, exponents, square roots, and the constants pi and e, along with parentheses.
How does it handle order of operations?
It follows standard precedence, so multiplication and division come before addition and subtraction, and parentheses override that order.
Are the trig functions in degrees or radians?
Check the mode setting. Trig functions expect radians by default unless a degree mode is selected.
