How it's calculated
Order of operations: ( ) → ! % → ^ (right to left) → × ÷ → + −
Expressions are parsed, never run as code. Powers group from the right (2^3^2 = 2^9) and before a leading minus (−2^2 = −4), and a number next to a bracket or a name multiplies it (2pi, 3(4+1)). log is base 10, ln is base e. x% means x ÷ 100. Factorials work up to 170!; anything larger is beyond the range of the calculator. Results are shown to 15 significant figures.

About the Scientific calculator
This online scientific calculator handles everything a handheld one does: trigonometry, logarithms, powers, roots, factorials and brackets. You can type an expression or tap the keypad. It follows the standard order of operations and parses your expression without running it as code. It shows the result to 15 significant figures, in scientific notation and rounded to 4 places. It works in degrees or radians, and understands shortcuts such as 2pi or 3(4+1), where a number next to a bracket or name means multiply. For a single operation, the exponent, logarithm and square root calculators show more working.
How to use it
- Type your sum in “Expression”, or build it with the keypad (sin, cos, tan, ln, log, √, xʸ, n! and more).
- Choose Degrees or Radians under “Angles” before using trigonometry.
- Read the answer, then its scientific notation and the value rounded to 4 places.
- Edit the expression to try variations; the result updates as you type.
Worked example
2^10 + sqrt(144) × sin(30) in degrees is 1,024 + 12 × 0.5 = 1,030. Switch Angles to radians and sin(30) becomes −0.988 instead of 0.5, which is the most common source of “wrong” trigonometry answers.

Questions people ask
What order does the calculator work in?
Brackets first, then factorials and percentages, then powers (right to left), then multiplication and division, and finally addition and subtraction.
Why is −2^2 equal to −4 and not 4?
The power is applied before the leading minus sign, so −2^2 means −(2^2) = −4. Write (−2)^2 if you want 4.
How do I switch between degrees and radians?
Use the “Angles” setting. sin(30) is 0.5 in degrees but about −0.988 in radians, so check it before any trigonometry.
What is the difference between log and ln?
log is the base-10 logarithm and ln is the natural logarithm, base e. ln(e^2) is exactly 2.
What is the largest factorial it can work out?
170!. Anything larger is beyond the range of numbers the calculator can hold, so it reports that there is no finite answer.
