Welcome to Earth, Population:5

What if someday, a horde of asteroids rained down on Earth. The whole world died, but Taiwan was spared luckily. Everyone else disappeared of the face of Earth. There were a few hundred people left on Earth, but they fought for food and resources so in the end only the strongest of the people survived. Five people were left and they decided to travel to other countries. Maybe it was coincident, but there were only five continents that they could live on. So the men had one continent for each person. The people built automatic robots to hunt and farm for them, each person had to trade to each other to survive, because there were things they could not grow or hunt. They were too busy to fly all the way over because they had to manage the robots in case the robots went haywire. So they sent planes with set destinations. The people managed survive for a 26 years, but then the robots did went haywire and killed them all.

Finding the answer is not aways the most important

Finding the answer is not always most important, because the journey to the answer is more important than the answer. Have anyone wanted to show you something but you don't know what that is. Imagine that thing is on a mountain and when you are climbing up the mountain, you are very excited but when you see that the thing is just a rock, you will realize that the result is not the most important but the journey is the most important. This is also the same as understanding the question. When you see a question, have to understand the calculations and not just finding the answer. If you understand the calculations, you can use the same calculations next time you see a question that is similar to the other question.
