(15 1/6 + 10 13/16 )-(15 1/6-10 13/16)=
(15 16/96+ 10 78/96)-(15 16/96 -10 78/96)=
(25 94/96)- ( 4 32/96)=
21 62/96=21 31/48

Suma wynik dodawania (1)
róznica wynik odejmowania
(1) 15 1/6 + 10 13/16 = 15 8/48 + 10 39/48= 25 47/48
(2) 15 1/6 - 10 13/16 = 15 8/48 - 10 39/48= 14 56/48 - 10 39/48=
=4 17/48

(3) odejmij (1) od ( 2 )

25 47/48 - 4 17/48 = 21 30/48 = 21 15/24
