Mmmm [17]
The calmer u are,the clearer u think, move with strategy,not with emotion

Let solve this:simplify 8n×2(2n)/4(3n) (0)
2(3n)×2(2n)/4(3n) 2(3n+2n)/2(2n)(3n) 2(5n)/2(6n) 2(5n-6n)=2-n Therefore 8n ×2(2n)/4(3n)=2(-n)

Appreciate those who gossip about u,it not easy for someone to leave their own problem and carry urs on their head

Silent [239]
The meaningful silent is better than the meaningless word
