                                                                                          NS 1.2

 

     Add, Subtract, Multiply and Divide Rational numbers (fractions, integers and terminating decimals) and take positive rational numbers to whole- number powers.

 

Student Definition of  NS1.2-

     Add, Subtract, Multiply and Divide fractions, positve and negative numbers and decimals with a final digit and take them to whole number exponents.

 

 

 

 

 

 Exemplar: Find the value of y.      

 

     -24 - 109y = -1441                     Write original problem.

 

     

 

     -24 + -109y = -1441                   Change all subtraction to addition by adding the opposite.

 

 

 

     -24 + -109y = -1441                    Add 24 to both sides to get -109y by itself. Add 24 to -1441.            

     +24                 +24 

         -109y = -1417

 

 

      -24 + -109y = -1441              Divide both sides by -109 so that y cancels and you get a answer of y = 13. 

    +24                +24 

       -109y=  -1441

         -109      -109

 

             y=13
