Răspuns :
D= descazut
s = scazator
d = diferenta
D - s = d
( D + 23,456 ) - ( s - 1,544) = d
D + 23,456 + s + 1,544 = d
D - s + 25 = d
D - s = d - 25
23,456 - 1,544 = 21,912
s = scazator
d = diferenta
D - s = d
( D + 23,456 ) - ( s - 1,544) = d
D + 23,456 + s + 1,544 = d
D - s + 25 = d
D - s = d - 25
23,456 - 1,544 = 21,912
