Frequently Asked Questions
What does ^ mean in math?
The caret symbol (^) represents exponentiation or raising a number to a power. For example, 3 ^ 2 means 3 raised to the second power ($3^2$), which equals 9.
What is ! in math?
The exclamation mark (!) denotes a factorial. The factorial of a non-negative integer is the product of all positive integers less than or equal to that number. For example, 5! = 5 × 4 × 3 × 2 × 1 = 120.
