Simplifies a complex fraction by multiplying the top and bottom by the common denominator of the smaller fractions so their denominators can be eliminated. Further simplification is considered.


This example shows how to factor each denominator and then determine which of these factors are needed to create the least common denominator (LCD). Then the fractions are expanded by multiplying…


A clarification on what common multiple means and why the least common one is larger than or at least as large as either number or expression. Then there follows an example of two multivariate…


A straightforward examplel of a simplification using the product rule for exponents.


Presents a compound inequality where both sides have to be solved for the variable first, and then shows how to graph the simplified results


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.


Shows how to create the simplest expression both of the given ones divide into.


This one helps you deal with fractions in an equation.


Three quick examples that show the order in which we simplify different opertions in arithmetic.


Three quick demos, two subtractions and an addition which need adjusting first to create a common denominator


The f irst basic addition/subtraction of fractions that don't have the same denominators.




This video explains why the order of operations needs to be the way it is, and then gives some examples of its use.
