Explicație pas cu pas:
Descazut+scazator+rest=320=>
Rest=320- (descazut+sczator)
Scazator=rest ori 4
Descazut-scazator= rest
Descazut-sczator= 320-(descazut-+sczator)
Desczaut-sczator=320-desczut-sczator
Dezcazut+desczaut-szacator+ sczator=320
2desczatut=320
Desczaut=320:2
Dezcazut= 160
160+ 4 ori rest+rest=320
160+5 rest=320
Rest= (320-160):5
Rest= 160:5
Rest= 32
160-sczator=32
Scazator=160-32
Sczator= 128
Verificare
Sczatorul=4 ori rest?
128=4 ori 32 ?
128= 128 (adevarat)
Desczaut+scazator+rest=320?
160+128+32= 320?
320=320 (adevarat)
