Using the Scientific Calculator
Use parentheses around function arguments, such as sqrt(9) or sin(pi/2). Keep an eye on angle units: the trigonometric functions here accept radians. A familiar degree value must be converted before it is used.

Method and assumptions
Order of operations: parentheses, powers, multiplication/division, addition/subtraction. Scientific functions: sin, cos, tan (radians), sqrt, abs, ln, log, exp; constants pi and e. Use * for multiplication.
Make the intended order explicit
Parentheses are the clearest way to show which operation should happen first. Enter multiplication explicitly where the parser requires it, and check the function names supported by the tool. When comparing with a handwritten expression, pay special attention to negative signs, exponentiation and angle units because they can change the meaning of an otherwise familiar calculation.
Common question
How do I calculate the sine of 30 degrees?
Convert 30 degrees to radians and enter sin(30*pi/180). Entering sin(30) directly treats 30 as radians and answers a different question.
