(5/2 - 1/4)  *  5/6 - (3- 7/6) = (10/4-1/4)*5/6-(18/6-7/6)

                                          = 9/4*5/6-11/6

                                          = 45/24-11/6

                                          = 45/24-44/24

                                          = 1/24

= (10/4-1/4) x 5/6-(18/6-7/6)

= 9/4 x 5/6-11/6

= 45/24-11/6

= 45/24-44/24

= 1/24
