Writing Equations

The essence of translating word problems into mathematical equations is crucial for GRE prep, focusing on understanding how verbal cues correspond to mathematical operations.
  • Translating words to math involves recognizing verbs like 'is' or 'are' as indicators of the equals sign in an equation.
  • Expressions such as '50 more than B' translate to mathematical operations differently than they appear in text, requiring a reversal in order (e.g., B + 50).
  • Understanding the mathematical representation of percentages and their operations is key, such as knowing that '50% of B' translates to 0.5 * B.
  • Solving complex word problems involves creating and manipulating equations based on the given information, often requiring algebraic setup before finding the solution.
  • The process of solving these problems is demonstrated through practice problems, highlighting the steps from translating the problem into equations to solving for the unknown.
