By the way, if you are not sure of spelling and grammar, you may write in Tagalog. Also, please read the term of use of this site, and you'll be enlightened. I answer mostly Math and English because I know that some textbooks, especially in public schools, are old editions and lack explanations and exercises for mastery of the lessons.
Finally, either you help or not. Use your discretion to answer questions you think deserve to be answered correctly, and leave those you think are coming from "lazy" students. Just don't call them "tanga". This site has moderators (volunteers, not paid); we delete questions repeatedly posted and warn or ban users violating the term of use of this site.
