1. -2 ( a + 6)  =  -2a  - 2*6  =   -2a  - 12

 

2.  Whole Numbers, Rational Numbers, Integers 

 

3. "6 Times the difference of B and p?"  =   6 [ b -  p ]

 

4. 5(14-2)^2/2  =  5 (12)^2 / 2  =  5 * 144/2  =  5 * 72 =  360

 

5.  u + xy, if u= 18 and x= 10, AND y=8

 

    18  + (10) (8)  =

 

    18  +  80  =

 

        98
