x + ( 28 + 3006 - 1200 ) = 5000                                                                                                                 
x + 1834 = 5000                                                                                         x = 5000 - 1834 = 3166                                                                                


x - ( 745- 3 x 8 ) = 100000                                                                                x - 721 = 100000                                                                                            x = 100000 + 721 = 100721                                                                         


( 265708 + 5 x 12 ) x 0 + x = 195277                                                             265768 x 0 + x = 195277                                                                             0 + x = 195277                                                                                             x = 195277 - 0 = 195277
