Interactive FAQ
What is the order of operations?
PEMDAS/BODMAS is the order of operations, which stands for Parentheses/Brackets, Exponents/Orders, Multiplication and Division (from left to right), and Addition and Subtraction (from left to right).
What does ln(x) mean?
ln(x) is the natural logarithm of x, which is the power to which the constant e (approximately equal to 2.71828) must be raised to produce x.
