Arithmetic Operations

Write a Java program to print the results of the following operations.

Sample Solution-1

Java Code:

public class Exercise4 {
    public static void main(String[] args) {
        // Calculate and print the result of the expression: -5 + 8 * 6
        System.out.println(-5 + 8 * 6);

        // Calculate and print the result of the expression: (55 + 9) % 9
        System.out.println((55 + 9) % 9);

        // Calculate and print the result of the expression: 20 + -3 * 5 / 8
        System.out.println(20 + -3 * 5 / 8);

        // Calculate and print the result of the expression: 5 + 15 / 3 * 2 - 8 % 3
        System.out.println(5 + 15 / 3 * 2 - 8 % 3);
    }
} 

Explanation:

The above Java code calculates and prints the results of four different arithmetic expressions:

• '-5 + 8 * 6' evaluates to '43'.
• '(55 + 9) % 9' evaluates to '1'.
• '20 + -3 * 5 / 8' evaluates to '19'.
• '5 + 15 / 3 * 2 - 8 % 3' evaluates to '13'.

Each expression is evaluated based on the order of operations (PEMDAS/BODMAS), which determines the sequence of arithmetic operations.

Note: PEMDAS stands for P- Parentheses, E- Exponents, M- Multiplication, D- Division, A- Addition, and S- Subtraction.

BODMAS stands for Bracket, Of, Division, Multiplication, Addition, and Subtraction.

Sample Output:

43                                                                                                      
1                                                                                                      
19

Sample Solution-2

Java Code:

public class Main {
  public static void main(String[] args) {
    // Calculate and store the result of the expression: -5 + 8 * 6
    int w = -5 + 8 * 6;

    // Calculate and store the result of the expression: (55 + 9) % 9
    int x = (55 + 9) % 9;

    // Calculate and store the result of the expression: 20 + (-3 * 5 / 8)
    int y = 20 + (-3 * 5 / 8);

    // Calculate and store the result of the expression: 5 + 15 / 3 * 2 - 8 % 3
    int z = 5 + 15 / 3 * 2 - 8 % 3;

    // Print the calculated values, each on a new line
    System.out.print(w + "\n" + x + "\n" + y + "\n" + z);
  }
}
