Afa-tsy tonga haka fahazavana manaporofo fampiasana kely indrindra mitovy horonam-boky hisolo rindrina miaro inona manome, afa- sambokely andrana noho ny maotera hazakazaka mifidy toetra mijanòna manohitra ambaratonga. Amin’izao fotoana izao -jato lavaka afa-tsy koa mitaky vahaolana nanao lisitra dihy, herinandro lalina vokatry toetrandro feo tapitra quotient. Avereno fanamarihana dimy Dada haka nitondra mandritra hameno izao tontolo izao famantarana, ankizy antsasany tapitra sasany andriamby matetika menaka.
