Answer:

Step-by-step explanation:

a) (8 + 9) X 10  = 17 X 10  = 170

   8 + 9 x 10   =  8 X 90  = 720

(8+9) X 10  <  8+ 9 X 10

b) {(-2) (-5)} + 10 = 10 + 10  =  20

  {(-2)+10) x (-5)  = 8 x (-5) = -45

{(-2) (-5)} + 10 >  {(-2)+10) x (-5)

2)  a) 15 x {7+ (-2)} = 15 x 7 + 15 X (-2)

         15 x { 5}  =  105  - 30

             75  =  75

b) (-23) {(-5) + 19} = (-23) X(-5)+(-23) x 19

     (-23) {14}    =    115 -  437

      -322    =  322

3)  a) (-161) + (-23)   =  -184

   b)   (-2) X(-4) (-6)  =  (-2)x24  =  -48

4)  a) 1535 x 39 + (-535) X 39   =  59865 + ( - 20865 ) = 39000

b)  38457 x 99-(-38457)   =  38457 x 38556
