7256*4375-725/3650+4375*7255
= 7256 * 4375 + 4375 * 7255 - 29/146
= 4375* ( 7256+7256) -29/146
= 4375* 14512 -29/146
= 63490000- 29/146
7256 x 4375 - 725
= 31745000 - 725
= 31744275
3650 + 4375 x 7255
= 3650 + 31740625
= 31744275
7256 * 4375 - 725 = 31745000 - 725 = 31744275
3650 + 4375 * 7255 = 3650 + 31740625 = 31744275
