  1. Simple Arithmetical Operations

    Slide 1 - Simple Arithmetical Operations

  2. Mathematical Operators

    Slide 2 - Mathematical Operators

    • Operator
    • +
    • -
    • *
    • /
    • %
    • ++
    • --
    • +=, -=, *=, /=
    • Meaning
    • Add
    • Subtract
    • Multiply
    • Divide
    • Remainder (Modulus)
    • Increment
    • Decrement
    • Similar to x = x operator y
  3. Modulus or Remainder Operator %

    Slide 3 - Modulus or Remainder Operator %

    • Returns the integer remainder of an integer division operation
    • 5 % 2 results in a value of 1 One is the remainder when 5 is divided by 2
    • 6 % 3 results in a value of 0 Six is evenly divided by three so there is a remainder of zero
    • 13 % 5 results in a value of 3 13 / 5 is 2 with a remainder of 3
  4. ++ and – the before and after

    Slide 4 - ++ and – the before and after

    • Increment
    • X++ Uses the current value of X and then adds one to the value of X
    • ++X Adds one to the value of X and then uses the new value
    • Decrement
    • X-- Uses the current value of X and then subtracts one from the value of X
    • --X Subtracts one from the value of X and then uses the new value
  5. Fun with the Equals Sign

    Slide 5 - Fun with the Equals Sign

    • Long Form
    • x= x + 5;
    • x= x – 5;
    • x= x * 5;
    • x= x / 5;
    • Short Form
    • X += 5;
    • X -= 5;
    • X *= 5;
    • X /= 5;
