Hello guys!! I am selling my 'Introduction to Logic' book!! The cover is yellow & green I forgot the author's name. Anyway I'll update this later to post a pic & the author's name. Ginamit namin yun sa lOgic subject namin nung first year first sem. Prof. namin nun si Sir Fietas>
By the way...it's only for 70.00 pesos. Wala na pong tawad!
