How can we implement arithmetic operations in Scala?

In Scala, addition, subtraction, multiplication, and division can be implemented using either operators or functions. Here are some common implementation methods:

1. Utilizing operators:

1. Addition: Using the “+” operator
   val result = a + b
2. Subtraction: Using the “-” operator
   val result = a – b
3. Multiplication: Use the “*” operator
   val result = a * b
4. Division: use the “/” operator
   val result = a / b

1. Use functions:

1. Addition: Using the “add” function
   def add(a: Int, b: Int): Int = a + b
   val result = add(a, b)
2. Subtraction: using the “subtract” function
   def subtract(a: Int, b: Int): Int = a – b
   val result = subtract(a, b)
3. Multiplication: Use the “multiply” function
   def multiply(a: Int, b: Int): Int = a * b
   val result = multiply(a, b)
4. Division: Use the “divide” function
   def divide(a: Int, b: Int): Double = a.toDouble / b.toDouble
   val result = divide(a, b)

Note: in the example code above, “a” and “b” represent two integers or floating point numbers, choose the appropriate data type based on the actual situation.
