Math Strategy: Picking Numbers - Part I

General Math Strategies
Summary
Picking numbers is a strategic approach in solving algebra problems, especially useful in equations or inequalities with variables in both the prompt and the answer choices.
- Picking numbers can simplify complex algebra problems by substituting variables with easy numbers, such as 0, to quickly eliminate incorrect answers.
- This strategy is particularly effective for inequalities and can be a significant time-saver on tests like the ACT math section, though it requires practice to become efficient.
- Using multiple methods to solve a problem deepens understanding and confirms the solution's accuracy.
- Choosing 'low-hanging fruit' or simple numbers for variables can immediately rule out several answer choices, increasing the odds of guessing correctly if unsure.
- Through strategic number picking and process of elimination, it's possible to isolate the correct answer without fully solving the problem algebraically.
