This file contains four basic arithmetic functions: sum, multiply, divide, and subtract. Each function takes two parameters and returns the result of the corresponding arithmetic operation.

Functions

sum(a, b)

This function takes two numbers as parameters and returns their sum.

Parameters:

• a (Number): The first number.
• b (Number): The second number.

Returns:

• (Number): The sum of a and b.

multiply(a, b)

This function takes two numbers as parameters and returns their product.

Parameters:

• a (Number): The first number.
• b (Number): The second number.

Returns:

• (Number): The product of a and b.

divide(a, b)

This function takes two numbers as parameters and returns the result of dividing a by b.

Parameters:

• a (Number): The numerator.
• b (Number): The denominator.

Returns:

• (Number): The result of dividing a by b.

subtract(a, b)

This function takes two numbers as parameters and returns the result of subtracting b from a.

Parameters:

• a (Number): The minuend.
• b (Number): The subtrahend.

Returns:

• (Number): The result of subtracting b from a.
