Why Order Matters
Imagine you're following a recipe: "Add 2 cups flour plus 3 times 4 tablespoons sugar". Do you add 2 + 3 = 5, then multiply by 4 to get 20 tablespoons sugar? Or do you multiply 3 × 4 = 12 first, then add 2 cups flour plus 12 tablespoons sugar? Without BIDMAS, mathematical expressions would be as confusing as this recipe! BIDMAS gives us the universal order that mathematicians worldwide follow.
