e) \( b y-c y-b+c \)

Did you know that algebraic expressions like \( b y-c y-b+c \) have roots deep in history? The ancient mathematicians of Babylon around 2000 BC were already solving linear equations, laying the foundation for the symbolic mathematics we use today! They may not have had \( b, c, y \) specifically, but their methods were remarkably similar. Now, for real-world applications, algebra helps in countless fields like engineering, economics, and even computer science. Resolving expressions like \( b y-c y-b+c \) can help in optimizing designs, budgeting expenses, or even programming algorithms. Whether you're designing a bridge or coding a game, mastering these expressions is a handy skill!
