Short talk Math

Valentines is over, so go and kill yourself. I received 3 bouq of flowers and 6 packets of chocolates so don't try to impress me by telling you got one Rm7.90 rose from a stranger. The flowers withered and the chocolate melted, I'm still single.... Now I'm quietly waiting for Chinese New Year so at the meanwhile, you go figure out why this guy can do math like that....
