Frequently asked questions
How do I calculate powers and roots?
Use ^ for powers, for example 2^10, and sqrt( ) for square roots. cbrt( ) gives a cube root, and you can write fractional powers like 8^(1/3).
Does it use degrees or radians?
Degrees by default. Press the Angle button to switch to radians. The setting is remembered on your device.
What is the difference between log and ln?
log is the base 10 logarithm and ln is the natural logarithm (base e). log2 is also available.
How do I calculate a percentage?
The % key divides a number by 100, so 50% equals 0.5. To find 20% of 80, type 80*20%.
Why do I see a Math error message?
Some operations have no real answer, such as dividing by zero, the square root of a negative number or the log of zero. Check the numbers and brackets in your expression.
