 * Assignment Operator:**
 * The assignment operator is the equals (=) sign
 * Ex.- int i = 3 assigns the value 3 to the integer i


 * Arithmetic Operations:**
 * Addition (+), subtraction (-), and modulus (%) are the three most basic arithmetic operations.
 * Modulus (%) takes the remainder of dividing the first operand by the second.
 * Ex.- 5%3 = 2 because 5/3 returns a returns 1 with a remainder of 2.
 * Other operations include multiplication (*) and division (/).
 * When dividing integers, the decimal portion of the answer is truncated, not rounded.
 * The rules of PEMDAS apply to computer computations.

NOTE: When the x++ and x-- operations are performed, the value of x is only changed AFTER the command has been carried out. Therefore, code format="javascript" int x = 1; System.out.println(x--); System.out.println(x); code actually prints: 1 0
 * Increment and Decrement:**
 * Incrementing a value increases its value by one. For instance, if the integer count has already been declared, inputting count = count + 1 is legal because it makes the NEW count the OLD count plus one.
 * Decrementing a value decreases its value by one. For instance, if the integer count has already been declared, inputting count = count - 1 is legal because it makes the NEW count the OLD count minus one.
 * ~ **Increment** ||= x = x + 1 ||= x++ ||= ++x ||
 * ~ **Decrement** ||= x = x - 1 ||= x-- ||= --x ||
