A short discussion of how compunde interest works and why the amount in a compound interest account grows more and more quickly.


Demonstrats how to free all perfect squar in a radical expression so they are whole.


A complex fraction is multiplied through on the top and the bottom by the common denominator of all smaller fractions, eliminating the denominators of those smaller fractions.


Each denominator is factored and then any common factor is used only once and all other unique factors complete the LCD


Expands each monomial as a list of all of its prime factors, then showing those that both lists have in common to develope the GCF.


A multivariable fraction that is reduced by applying the quotient rule and the definition of a negative exponent.


Two examples of expressions with negative exponents that are changed to expressions with positive exponents, leaving the numerical factor as is.


This describes how to solve each side of a compound inequality, then using the graphs of each part determine the interval notation for the entire compound statement.


A demonstration of how to deal with interpreting the union and intersection of two inequalities. For a more extensive and exhaustive demo, please view the videos entitled "Understanding…


A brief description of the difference between rational and irrational numbers followed by examples of number in both categories.


A two step process is shown here. First, as always, look for a greatest common factor (GCF) and remove it from all terms. Then second, the resulting quadratic expresssion can then be factored into…


The key to getting this type of question is distributing any minus sign on the outside of the parentheses to each term on the inside thereby changing all of the i nner signs to their opposite


Shows how to write the domain and range of a graph of an unbroken function with a starting point and an ending point.


Some examples of what to do when subtracting a negative number and more examples of adding or subtracting fractions


How to add o r subtract two fractions with like denominaotrs and then reducing the result as needed.
