Type an expression or tap the keys to work with trigonometry, logarithms, powers, roots and factorials. Switch between degrees and radians, and reuse your last answer.
Results are estimates for planning. Check the figures before you make a financial or health decision.
How the Scientific calculator works
You can type a full expression, such as 2*(3+4)^2/sqrt(16), or build it with the keys. The result updates as you type, and pressing equals stores it so you can reuse it with the Ans key.
The calculator follows the usual order of operations: brackets first, then powers, then multiplication and division, then addition and subtraction. It supports:
- Trigonometry: sin, cos, tan and their inverses asin, acos and atan.
- Logarithms and exponentials: ln (natural log), log (base 10) and exp.
- Powers and roots: ^ for powers, sqrt and cbrt.
- Other: abs, percentages with %, factorials with !, and the constants π and e.
The Deg/Rad button switches between degrees and radians for trigonometric functions. Factorials need a whole number from 0 to 170. The calculator works in standard floating-point arithmetic, so very long decimals are rounded for display and tiny rounding errors can appear.
Tips and common mistakes
Check the Deg/Rad setting before any trigonometry. The same sin(30) gives 0.5 in degrees mode and a very different answer in radians. It starts in degrees.
Use brackets freely, especially around fractions and negative numbers, because they make the order of operations explicit. For everyday sums, the Basic calculator calculator is simpler. For fractions, Fraction calculator gives the answer in its simplest form.
Frequently asked questions
Does it use degrees or radians?
It starts in degrees. Press the Deg button to switch to radians, and press it again to go back.
Can I type an expression instead of pressing keys?
Yes. Type it into the expression box, using * for multiply, / for divide, ^ for powers and sqrt( for square roots.
What is the largest factorial it can do?
Factorials work for whole numbers from 0 to 170. Beyond that the result is too large for the calculator to handle.
