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.
