{[a:2)+a]:3}:4=10
[(a/2+a):3]:4=10
(a/2+a):3=10x4=40
a/2+a=40x3=120
a+2a=240
3a=240
a=80
sti cum era {[(a:2)+a]:3}:4=10
{[(a:2)+a]:3}:4=10,[(a:2)+a]:3=10x4=40,(a:2)+a=4x3=120,a/2+a=120,a+2a=240,3a=240,a=80
a:2=a/2
sau:(a:2)+a=120,a:2=120-a,a=(120-a)x2=240-2a,a+2a=240,3a=240,a=80, e cel mai bun?
foarte bun
