Part 2: Arithmetic Practice

Write a Java program to calculate these:

  1. num1 = 10
  2. num2 = 5
  3. sum = num1 + num2
  4. difference = num1 - num2
  5. product = num1 * num2
  6. quotient = num1 / num2
  7. Display all results using System.out.println().

Example Output:

Sum: 15
Difference: 5
Product: 50
Quotient: 2

Part 3: Step-by-Step Sequencing

Write a Java program that does this sequence:

  1. Set num1 = 2 and num2 = 3.
  2. Calculate num3 = num1 + num2.
  3. Calculate num4 = num3 * 2.
  4. Display num3 and num4 using System.out.println().

This shows sequencing: each step depends on the previous one.

Part 4: Mixed Arithmetic

  1. Set a = 8, b = 4, c = 2.
  2. Calculate:
    • result1 = a + b * c
    • result2 = (a + b) * c
  3. Display result1 and result2 using System.out.println().

This helps practice order of operations.
