As you are new here, I am creating this thread for you to introduce yourself.
Also, I have moved your 4 P6 Math questions into the PSLE Math thread here:
http://www.kiasuparents.com/kiasu/forum ... start=3380
You can post all your questions there, somebody will pick it up and solve it so no worries about it going unnoticed in a thread. You just need to check it diligently for the solution that you want as sometimes the thread may move fairly quickly. Hope you enjoy your stay here. Thank you.
