Universal Truths
Mathematical constants are values that remain fixed in any mathematical context. They represent deep patterns in nature, logic, and geometry. Unlike variables, these 'special numbers' define the very framework of our universe.

Pro Tips
Ο (Pi) relates the circumference of a circle to its diameter.
e (Euler's Number) is the base of natural logarithms and exponential growth.
Ο (Phi) is the golden ratio, found in art, architecture, and biology.

Fun Facts
"The number Ο has been calculated to over 100 trillion decimal places."
"Euler's number e is sometimes called 'the most important number in mathematics'."
"Constants like 'i' (imaginary unit) allow us to solve equations that have no real solutions."
Formula: Constants are fixed: Ο β 3.14, e β 2.71, Ο β 1.61
