Addition and subtraction have equal priority in order of operations! When operations have the same priority, you must work left to right. This is like reading - you go from left to right.
You'd get 7 + (-2) = 5, which happens to be correct! But this method can lead to mistakes with bigger numbers. Always follow left-to-right order to avoid confusion.
Great idea! Writing (7 + 2) - 4 = 9 - 4 = 5 shows your thinking clearly. Parentheses help you organize your work and catch mistakes.
Think of it like reading a sentence - you start on the left and move right! For math expressions with same-priority operations, follow the same rule.
Multiplication and division would come before addition and subtraction. But among themselves, multiplication and division also follow left-to-right order.
