9+(9•3)+[3+(9•3)]+{9+(9•3)+[3+(9•3)]}=
9+ 27+30+{9+27+30}=
9+27+30+66= 132, deci veverița a adunat 132 de alune.
9+ 27+30+{9+27+30}=
9+27+30+66= 132, deci veverița a adunat 132 de alune.
9x3=27 alune ( adunate a doua zi)
27+3=30 alune ( adunate a treia zi)
9+27+30= 66 alune ( adunate in a patra zi)
9+27+30+66=132 alune ( are veverita in total)
27+3=30 alune ( adunate a treia zi)
9+27+30= 66 alune ( adunate in a patra zi)
9+27+30+66=132 alune ( are veverita in total)
