Key points
- Variables represent unknown values and allow us to generalize mathematical relationships.
- Equations state that two expressions are equal, and solving them involves finding the values that make the equation true.
- Understanding the order of operations (PEMDAS/BODMAS) is crucial for evaluating expressions correctly.
- The distributive property allows us to expand expressions and is a fundamental tool for simplifying and solving equations.
