I would like to send my sincerest apologies to all the followers and users of this blog for not being able to post new worksheets since Typhoon Glenda hit. We experienced a long power outage, a computer breakdown, and trouble with our internet service provider. Since we've recently acquired the service of a new ISP, the posting of new worksheets will resume soon. Thank you very much for all your comments. I am sorry I was not able to reply to all of them, but know that I appreciate them.
