egalam segmentele
390-6=384
aflam primul numar:
384:4=96
aflam al doilea numar:
96+1=97
aflam al treilea numar:
97+1=98
aflam al patrulea numar:98+1=99
v:96+97+98+99=390(corect)
a+b+c+d+e=130(pare)

rgalam segmentele
130-20=110
aflam primul numar:
110:5=22
aflam al doilea numar22+2=24
aflam al treilea numar 24+2=26
aflam al patrulea numar26+2=28
aflam al cincilea numar 28+2=30
v:22+24+36+28+30=130
corect,succes!
