Yesterday one friend reviewed my site and remarked that I am doing math homework for children and in his opinion it is not fair. To some extent he is correct because it can lead to undesirable character traits if it promotes cheating by just copying. But please note that I do not, “do math homework” for “them”. I explain concepts, show them how to set up a problem, give hints, and try to get them started. There are children who can not do all the homework for themselves because it is not always been given by the individuals capacity. But if we provide some good “help” they may be able to do it. I may give the answers, so that they can check their work.
I am not providing voluntary help.. Nobody will simply throw their money if they really don’t want this service. So nobody will seek the help without even try to do it. I think children who really need the help only write to me. And I hope, students, you use this service in a good manner only, if not I request you to don’t misuse my service.
Good luck and happy learning.

There are two doors. Behind one is safety; behind the other is certain death. There are two guardians of the doors; one is known to always tell the truth. Other always lies. You have only one question to ask to find out which door is safe to go through.
What question do you ask?
Answer:
Would the other guard say that this is the safe way to go?
(answer will be same for both the guardians. If the answer is “yes” go the other way; if the answer is “no” go the same way.)

A snail climbs up at the rate of 2 feet per hour throughout the day and falls down half the distance in the night. How much time will it take to reach the top of a pillar 60 feet height?
