For the percent example at 11:00. I thought 30% off means multiplying 70 by .30 and same for 20% off from the coupon. But, instead you did 100% - 30% = 70% and multiply 70 by .70, why is that? Can you explain it pls?

Post by Tommy Lunceford on April 15, 2014

During the Domain and Range example, does the +3 change to a negative -3 just because its under the square root sign or because of the negative in front of the square root symbol?

If that negative sign in front of the square root symbol was not there, would it still turn into a -3 or remain positive as it is under the square root symbol?

Thank you

Math Concept Petting Zoo: Part 1

  • If you want to do well on the Math section of the SAT, you need to be familiar with a wide variety of concepts. This is the first of two lessons covering the vast majority of the concepts on the SAT.
  • In the first lesson, we'll generally cover topics relating to the interaction of numbers, equations, and functions. The second lesson will focus more on geometry, shapes, and a few miscellaneous topics.
  • In the Zoo, each concept will be presented by showing a question based on the concept. While there will be some explanation of the questions, the point of the Zoo is to quickly review concepts, not teach them.
  • As you watch this lesson, make sure you have a pencil and paper. Make sure you could solve each problem on your own before the answer is revealed. If you're not absolutely certain you could, pause the video and try to work it out yourself before you continue watching.
  • Whenever you find a concept you don't know well, write it down and note how much help you need.
  • Later, after you've finished watching the lesson, go study the concepts you wrote down. Begin with the ones you find most difficult. Watch the corresponding SAT Math-specific lessons, and if you still need more help, browse Educator.com, search the web, or talk to someone who is good at math.
  • Here's a list of all the concepts in this half of the Zoo:
    • Intersection and Union,
    • Sequences / Patterns,
    • Even/Odd Properties,
    • Primes,
    • Percent,
    • Percent Change,
    • Average: Mean, Median, Mode,
    • Absolute Value,
    • Solving Equations for Unusual Things,
    • Distance = Speed · Time,
    • Radicals,
    • Exponents,
    • Concept of a Function,
    • Domain and Range,
    • Function Transformations,
    • Expanding Factors (aka: FOIL),
    • Factoring,
    • Solving Polynomials.
