Period 2-3

 

 

Standard NS 1.2

Add, subtract, multiply, and divide rational numbers (integers, fractions, and terminating decimals) and take positive rational numbers to whole-number powers.

 

My meaning of NS 1.2

Able to add, subtract, multiply, and divide fractions, decimals, postive and negitive numbers and use exponets.

 

 

 

          8+6(8-11)+(-4)=

 

         =8+6[8+(-11)]+(-4)=      Step1. Change all subtraction to addition.

 

         =8+48+(-66)+(-4)=        Step2. Distribute 6 to the 8 and the -11.

 

           =8+(-12)+(-4)=              Step3. Add 48 and -66.

 

         = 8+(-16)=                    Step4. Add -12 and -4.

 

         = -8                              Step5. Add 8 and -16.
