The value of -1 ( 1+ 2(2)-1 (2) ) - -1 ( 1+ 2 ( 12 )+1 ( 12 ) ) is equal to

Answer

(3) - 54

2 ( 2, ) 2 < 0 1 + 2 2 = | 2| = - 2

First argument = - 2 - 1 2 = - 1 + 2 2 = - 2 2 12 1 1 = - 1

-1(- 1) = - -1( 1) = - 1 ( 1 (0, ))

12 (0, 2 ) 1 + 2 12 = 12

Second argument = 12 + 1 12 = 1 + 12 12 = 2 2 142 14 14 = 14

-1 ( 14 ) = 14

Value = - 1 - 14 = - 54
