OPPOSITE, NEGATIVE, and SUBTRACT. TO deal with DIVISION we sometimes need to change it to MULTIPLICATION of the RECIPROCAL  (FLIP THE SECOND NUMBER) Knowing what "-" belongs to is very important we can then apply PEMDAS in the correct way ************************* OPPOSITE OF *********************************** ************************* NEGATIVE *********************************** ************************* SUBTRACTION ******************************* ******************************************** * ************************* what do I call "-" it ******************************* ************************* picture #1 below *********************************** ************************* picture #2 below *********************************** ********************* SWITCH DIVISION ******************************* ************************* picture #4 below *********************************** ************************* picture #5 below *********************************** *************...

*******************************************   Understanding the INEQUALITY  Graphing an Open Sentence that is an INEQUALITY. (Marking all NUMBERS that will MAKE the INEQUALITY TRUE .) For example: Graph the Solution Set for   " 5 <  x " "  the >  or < will NOT ALWAYS point in the direction of the shaded solution.  SINCE   "5 < x" is EQUIVALENT TO   " x > 5 " the graph is  ... By READing the inequality starting with "X". " 5 < x " would be read "X is GREATER than 5." Since we are graphing "X's" , this method of translation will lead to the correct direction of the ARROW in the graph. OR TESTING A FEW NUMBES  Back into the ORIGINAL PROBLEM to be sure that they MAKE IT TRUE ********************************************************* ****************************************************** ******************************************************** As can be seen in the above video, some problems...
