An arithmetic program is a set of instructions that performs arithmetic operations, such as addition, subtraction, multiplication, and division, on numbers. Here's an example of a simple arithmetic program: *Program:* Calculate the sum of two numbers 1. Input two numbers, `a` and `b` 2. Add `a` and `b` together, storing the result in `sum` 3. Output the value of `sum` *Example code:* ``` // Input values a = 5 b = 3 // Calculate sum sum = a + b // Output result print(sum) // Output: 8 ``` *Arithmetic Operations:* 1. Addition: `a + b` 2. Subtraction: `a - b` 3. Multiplication: `a * b` 4. Division: `a / b` 5. Modulus (remainder): `a % b` *Example Programs:* 1. Calculate the area of a rectangle: `area = length * width` 2. Calculate the average of three numbers: `average = (a + b + c) / 3` 3. Calculate the distance between two points: `distance = sqrt((x2 - x1)^2 + (y2 - y1)^2)` These programs can be implemented in various programming languages, such as Python, Java, C++, or eve
