Summary
Understanding and solving problems with strange operators in advanced algebra is crucial for GRE prep, focusing on the interpretation and application of newly defined symbols according to given rules.
  • Strange operators are symbols in math problems that are unfamiliar and have a specific rule defined by the test for their use.
  • The key to solving these problems is to not panic, understand that the symbol is new to everyone, and closely follow the rule provided by the test.
  • Practice problems demonstrate how to apply the rule to find the value of expressions involving strange operators, emphasizing the importance of order of operations and simplification.
  • Examples include operations defined by symbols like star (*), arrow, and Greek letters, each with a unique rule for combining numbers.
  • The process involves basic arithmetic and algebra once the rule is understood, highlighting the necessity of keeping a level head and methodically applying the given rule.
