🎬 Video Tutorial

  • (0:16) Mathematical Expressions: Use terms and operators to represent calculations, helping solve real-life problems.
  • (0:30) Order of Operations: Follow BIDMAS: Brackets, Indices, Division/Multiplication, and Addition/Subtraction to ensure the correct calculation order.
  • (1:22) Left-to-Right Rule: When only Division/Multiplication or Addition/Subtraction are involved, solve from left to right.
  • (2:07) Nested Brackets: When multiple brackets are present, start with the innermost, then work outward, applying BIDMAS at each step.
