How to use it
Build an expression such as 2 + 3, sin(30), log(100), 2^10 or 5!. Press = Calculate for the result. Use Clear to start a new expression, and Clear history to remove past calculations. Angles are measured in degrees, which is the setting most school and everyday problems expect.
Tips
Check your brackets in longer expressions, especially when mixing powers and trigonometry. Remember that log() is base 10 and ln() is the natural logarithm. Factorial works for whole numbers from 0 to 170. If you see an error message, it usually means a bracket is missing.
