Scientific Calculator
About Scientific Calculator
A complete scientific calculator that runs in your browser. Use trigonometric functions (sin, cos, tan and their inverses), logarithms (log base 10 and natural ln), exponents and roots, factorials, constants like π and e, and parentheses to group sub-expressions. The calculator honours the standard order of operations (BODMAS/PEMDAS), so complex expressions evaluate correctly. Useful for students, engineers, and anyone who needs more than the four basic operations. No install, no signup.
How To Use

Who Uses Scientific Calculator
- Students and professionals who want private calculators with clear workings.
- Anyone doing everyday math without apps or data collection.
- People who prefer private — files and text stay on your device and are never uploaded to a server.
Frequently Asked Questions
Does it follow the correct order of operations?
Yes. The calculator evaluates expressions using standard BODMAS/PEMDAS rules — brackets, orders (powers/roots), division and multiplication, then addition and subtraction. Parentheses let you override the order.
Which functions are available?
Trigonometry (sin, cos, tan and inverses), logarithms (log and ln), exponents, roots, factorials, and the constants π and e. Degrees and radians are both supported for trig functions.
Can I use it for exams?
That depends on your exam rules. This calculator handles the maths most scientific calculators do, but always check whether your exam permits online tools.
Do I need to install anything?
No. The calculator runs entirely in your browser on any device, including phones and tablets.
