Summary
The content focuses on the concept of remainders in division, particularly when dividing by a number that is not a factor of the dividend, and introduces key formulas and strategies for solving GMAT problems involving remainders.
  • Explains the difference between dividing by a factor and a non-factor, introducing mixed-numeral and integer quotients.
  • Defines key terms such as dividend, divisor, quotient, and remainder, emphasizing the remainder must be less than the divisor.
  • Presents the formula to connect integer quotient and mixed-numeral quotient, highlighting the importance of understanding the non-integer part of the quotient.
  • Discusses generating examples of dividends for a given divisor and remainder, and the application of remainders in various contexts.
  • Introduces the 'rebuilding the dividend' formula as a crucial problem-solving tool for GMAT questions.
