## Assigning Variables

Summary

The content focuses on the algebraic approach to solving word problems for the GRE exam, emphasizing the strategic selection of variables to enhance problem-solving efficiency and accuracy.

- Algebra is presented as a widely applicable method for solving word problems, though not the only method.
- Choosing meaningful variables is crucial for clarity and to avoid confusion when solving word problems.
- Variables should be chosen based on the context of the problem, such as using initials for names or selecting a variable that represents the smallest or target value.
- Solving word problems effectively involves experimenting with different variable assignments to build intuition and find what works best.
- A detailed example illustrates how assigning variables based on the conceptually central quantity in a problem simplifies the solution process.
