Khan Academy
More Examples of Addition and Subtraction of Polynomials, Algebra II
Though they " sound like a really fancy word," polynomials prove to be no match for Sal's mathematical skills. After defining the term and providing a few examples, Sal works through a few equations that add or subtract polynomials,...
Khan Academy
Graphs of Square-Root Functions, Functions and Their Graphs, Algebra II
Though Sal expects viewers to be "reasonably familiar" with square roots, he takes this opportunity to explain some of the notation and how to graph square root functions. He uses a graphing calculator from my.hrw.com/math06 to...
Khan Academy
Newman Projections, Alkanes, Cycloalkanes, and Functional Groups, Organic chemistry
Sal starts this video with a short 3D methane molecule structure review. He then continues to demonstrate possible configurations for ethane. A ball-and-stick model is drawn, and viewers will find the labeling of bonds helpful as a...
Khan Academy
Solving Percent Problems, Decimals, Pre-Algebra
Converting percents to decimals, and the other way around, can be tricky. Sal shows young mathematicians how to simplify this process with two sample equations and one word problem.
Khan Academy
Solvent Effects on Sn1 and Sn2 Reactions
Sal reviews the Sn1 and Sn2 reactions with comparable reactants. He discusses which electrons are lost or gained and the conditions that make one or the other process favorable.
Khan Academy
Introduction to Ratios, Ratios, Rates, and Percentages, 6th Grade
Demonstrating the concept of ratios with several simple examples (animals, fruit, girls and boys in class), Sal guides viewers through finding and simplifying ratios. Even those who have difficulty grasping the concept of ratios will...
Khan Academy
Banking 18: Big Picture Discussion
Sal further ponders the meaning of wealth in this video, which explores the values of gold, land, and money. Touching on Adam Smith's definition of wealth, the presentation discusses the philosophy of utility and what different media of...
Khan Academy
Exponent Properties Involving Products, Numbers and Operations, 8th grade
After a short review of exponents, Sal incorporates exponent properties into his sample problems. This video is a great resource for those who need Sal's steady pace of instruction and the challenge of more complicated problems.
Khan Academy
Nucleophilicity (Nucleophile Strength)
Sal explains the details that affect nucleophile strength. He gives examples of electronegativity producing a fluorine anion, iodine becoming iodide, and a molecule such as the hydroxide ion. He compares their polarity, basicity, and...
Khan Academy
Example: Two-Step Equations, Linear Equations, Algebra I
Sal adds a few more steps to these problems as he solves algebraic equations with two steps, though he states that "there's more than one way to do it." Those who become confused by increasingly complicated algebra problems on a test...
Khan Academy
Stereoisomers, Enantiomers, Diastereomers, Constitutional Isomers and Meso Compounds
Sal works through a list of examples that demonstrate and review the different types of compound classification.
Khan Academy
The Discount Rate, Money, Banking and Central Banks, Finance and Capital Markets
What happens when a bank outlends its reserves? Sal answers this question in a video about the discount rate, explaining that it serves as the "lender of last resort" and outlining the possible circumstances that may necessitate such a...
Khan Academy
Graphs of Linear Equations, Linear Equations and Functions, 8th grade
Sal is plotting away in this video - but don't worry, it's nothing suspicious. He introduces linear equations, taking viewers through a few simple examples before applying the knowledge to more complex word problems.
Khan Academy
Pythagorean Theorem, Right Triangles and Trigonometry, Geometry
In this video, Sal introduces the Pythagorean Theorem to viewers, crossing into the realm of geometry. He uses several examples, including right triangles, to illustrate the applications and uses of the Pythagorean Theorem.
Khan Academy
Nucleophilicity vs. Basicity
After introducing basicity in the last video and generalizing it as closely related to nucleophilicity, Sal studies electron donors and the stability of both products and reactants. He compares and defines the two terms.
