Quantitative Problem Solving: So Easy a Child Could Do It
5 reviews

Not a child genius? Not a problem.  My name is Corey and I’m here to guide you through an interactive course on quantitative problem solving for mastering the math section of the GRE and GMAT exams.  This is vitally important for anyone planning on applying to most graduate programs. This course has GRE and GMAT math questions with fully annotated solutions.  This course is also ideal for high school students preparing for the SAT, as many of the harder math questions on the SAT will seem simple after mastering these questions. Feel free to preview sample solutions so that you have an idea of what to expect in the rest of the course.  Thank you for your time and I look forward to helping you maximize your math proficiency.

    Permutations and Combinations
    05:40

    This lecture will cover the derivation of the formulas for permutations and combinations.  Permutations represent selecting objects from a set of objects and the order of selection IS important.  Combinations represent selecting objects from a set of objects and the order of selection is NOT important.

    n Permutation x = n! / (n-x)!

    n Choose x = n! / ( (n-x)! * x! )

    Prime Factorization: GCF and LCM
    11:49
    Prime factorization is when you split a number into its prime factors.
    A prime number is a number that is only divisible by 1 and itself.  2 is defined as the first prime number.
    The factors of a number are the numbers that evenly divide into that number.  For example, the factors of 10 are 1, 2, 5, and 10.
    The prime factorization can be used to find the greatest common factor (GCF) or the least common multiple (LCM) of two or more numbers.
    The GCF can be used to simplify fractions.
    The LCM can be used to find a common denominator to add or subtract fractions.

    Exponent Rules
    06:33

    The most important exponent rules are covered in this lecture.  The most important rules are:
    1.  Add the exponents when you have two numbers with the same base multiplied together.
    2.  Subtract the exponents when you have two numbers with the same base divided by each other.
    3.  Multiply the exponents when you have an exponent raised to an exponent.
    4.  Negative exponents can be made positive by moving the number from the numerator to the denominator or vice versa.
    5.  Radicals can be changed into fractional exponents and vice versa.

    Combined Rate and Work Problems
    05:43
    Combined rate / work problems are used to add or subtract the rates of different people when they are doing the same task.

    Remember that when you add or subtract the fractions, the time component has to be in the denominator, on the bottom.  For example, 5 miles per hour + 10 miles per hour = 15 miles per hour.  Do NOT do: 1 hour per 5 miles + 1 hour per 10 miles = 3 hours per 15 miles.
  • 6
    Triangles
    10:15

    This lecture covers the most important subtopics for dealing with triangles.
    1.  A triangle has three sides and the sum of its angles is 180 degrees.
    2.  The area of a triangle is 1/2 * base * height.
    3.  Pythagorean's Theorem for right triangles: c^2 = a^2 + b^2.
    4.  An exterior angle for a triangle is equal to the sum of the other two angles.
    5.  There are two special triangles in terms of angles:

    45:45:90 triangle = x : x : x*sqrt(2)
    30:60:90 triangle = x : x*sqrt(3) : 2x
      6.  Any side of a triangle must be less than the sum of the other two sides of the triangle and more than the absolute value of the difference between the other two sides of the triangle.

    Fraction Arithmetic
    07:22
    This lecture covers fraction arithmetic.
    1.  To multiply fractions, multiply the numerators and denominators straight across.
    2.  To divide fractions, change the fraction being divided into its inverse, and then multiply the fractions straight across.
    3.  To add and/or subtract fractions, find the LCM (least common multiple) of the denominators, change all fractions so that they share this LCM, then perform the addition and subtraction operations only on the numerators, not the denominators.

    Divisibility Rules
    06:21

    This lecture will cover divisibility rules.

    2: The number is even; the number ends in 0, 2, 4, 6, or 8.

    3: The sum of the digits of the number is divisible by 3.

    4: The last two digits is divisible by 4.

    5: The last digit is either 5 or 0.

    6: The number is divisible by both 2 and 3.

    9: The sum of the digits is divisible by 9.

    10: The number ends in 0.

    GRE Quantitative Comparison Strategies Lecture
    06:10
    This lecture covers GRE quantitative comparison strategies.

    1.  Always use your pencil and paper.
    2.  Add or subtract any number from both sides to simplify the problem.  Usually this is useful if you have the same number, variable, or equivalent expression on both sides.
    3.  Multiply of divide any positive number, variable, or expression from both sides to simplify the problem.  Sometimes this is optional, but other times this is essential for solving a problem.  Remember that it must be a positive number, variable, or expression, as doing this with a negative number change the problem being asked.
    4.  Have confidence.  The GRE test is also a psychological test of your math ability and confidence level.  Not being confident in your math skills leads to double and triple checking answers, thereby taking away time from the other questions in the test.

    The visuals and the fact that I can go back to the lectures whenever and how many times I want for review after tutoring sessions is very helpful for me and good reinforcement.

  • Andrew Richards
    Everything you need for GRE Math, great practice problems

    Corey covers all of the math concepts that you might find on the GRE. He is skilled at breaking them down in a way that's understandable and applicable on actual GRE questions. Same with his solutions to the practice problems - he's great at picking out the underlying equations that the word problems are masking, so that you can understand the simplest (and surest) way to approach similar questions on the GRE. I would take more of his courses if they were on here!

  • Hasmik Sargsyan
    Great course! very easy to understand difficult problems

    I highly recommend using Corey's course--he breaks down the problems into details which are essential in understanding both the concept and building a strong groundwork for future similar problems. His tactics are very useful as well. With practice, I am sure that I will master solving the problems faster which is a key in getting a good GRE score. Thanks Corey!

  • Noreen Connolly
    Awesome Instructor!

    Corey is very clear in his instruction, and speaks slowly so the problems are easier to grasp. I have purchased Coreys classes in other forums and he never disappoints.
