๐Ÿ“š Quick Study Guide

  • ๐Ÿงฎ A variable is like a container that holds a value (e.g., a number).
  • ๐Ÿท๏ธ You assign a value to a variable using the equals sign (=). For example, `x = 5` assigns the value 5 to the variable x.
  • โž• You can perform calculations with variables, like addition, subtraction, multiplication, and division.
  • โž• Addition: `result = x + y`
  • โž– Subtraction: `result = x - y`
  • โœ–๏ธ Multiplication: `result = x * y`
  • โž— Division: `result = x / y`
  • ๐Ÿ”ข Remember the order of operations (PEMDAS/BODMAS): Parentheses/Brackets, Exponents/Orders, Multiplication and Division, Addition and Subtraction.
