Scientific Calculator
A full scientific calculator in your browser. Type or tap expressions with trig, logarithms, powers, roots and factorials, switch between degrees and radians, and reuse previous answers.
History
How to use the scientific calculator
- Type an expression or tap the keys. Use parentheses to group, ^ for powers and ! for factorials.
- Choose DEG or RAD for trig functions.
- Press = or Enter. Tap an entry in the history to reuse it, and use Ans for the last result.
Functions and order of operations
The calculator follows standard order of operations: parentheses, exponents, multiplication and division, then addition and subtraction. Exponents group right to left, so 2^3^2 is 2^9 = 512. Implicit multiplication works too, so 2π and 3(4+1) are understood.
Supported functions include sin, cos and tan and their inverses, sinh, cosh and tanh, log (base 10), ln (natural log), log2, sqrt, cbrt, abs, exp, factorials (!) and percent (%). Constants π and e are available, and Ans holds the last answer.
Results are shown with up to 12 significant digits. Like all floating-point calculators, tiny rounding errors can appear in the last digits, so values like sin(180°) are rounded to 0.

Frequently asked questions
Does it use degrees or radians?
Your choice: switch with the DEG and RAD buttons. Degrees is the default.
Can I use my keyboard?
Yes. Type expressions directly and press Enter for the result.
How do I calculate a power or root?
Use ^ for powers (2^8), sqrt() for square roots and cbrt() for cube roots, or x^(1/n) for nth roots.
What is the difference between log and ln?
log is base 10; ln is the natural logarithm, base e.
