x = -7/8  so | x | = 7 / 8
y = -3/5  so | y | = 3/5
Add  |x| + |y| =  7/8  + 3/5  =  (  7 * 5  + 3 * 8 ) / 8 * 5        = 59 / 40

                 |      7        3   |        |    - 7*5  - 3 * 8  |
| x + y  |  = |  -  ---    -  ----  |  =   |      --------------    |  =  |  - 59 / 40 |
                 |      8        5   |        |          40          |
     = 59 / 40

So both are same.  verified.

(-7/8(-3/5)).......-7/8-3/5......-(35/24)/40.....-11/40....(-7/8)+(-3/5)....-7/8-3/5.....-(35/24)/40.......-11/40...
