Arithmetic operators are used to perform mathematical operations on numbers. Addition (+), subtraction (-), multiplication (*), and division (/) are the basic arithmetic operators. Modulus (%) returns the remainder of a division. Exponentiation (**) raises a number to the power of another. Increment (++) and decrement (--) operators increase or decrease a number by 1, respectively.
