A demo that shows how to substitute possible xy ordered pairs into an equation to find out whether they create a true statement, determining which are solutions and which are not.


Just a short demo of how read the location of an (x, y) point on a Cartesian coordinate graph


This states the Multiplicative Propery of Inequality, then demonstates how it works with two examples.


A review of the sign rules for multiplication and three examples to demonstrate these.


This discusses what rationals and irratioinals are, then goes on to demonstrate how to eliminate any radical number in the denominator.


This demonstrates how to convert negative exponents in a complex fraction to the reciprocal positive exponents and then use the LCD of all fractions to simplify.


Application of the equation relating the three sides of a right triangle:: a^2 + b^2 = c^2 where a and b are the shorter sides that make the rigiht angle and c is the lenght of the longest side.


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…


Just an exercise in testing whether an ordered pair makes an inequality statement true when plugged in for the variables.


Demonstrates how to make t his graph per instructions, and also shows how to deal with a fractional leading coefficient.


A second example of how to use multiplication or division to isolate a chosen variable in a formula.


Describes multiplying or dividing both sides of an quationn by the same value in order to get the variable alone on one side


The beginnings of understanding how to solve equations by doing something to both sides, keeping it equal


Just add the two together and dvide by two, but this is also handy to find the halfway point between two numbers on a number line.


Fraction conversions that are simpler than they look.


Conversions using money as a way to think them through.
