Math Inspector - Who is the king of the forest

The python was like a dark cloud hanging over the forest, which had dissipated, the sun was shining, the animals were singing and laughing, and everywhere was a joyful scene. Inspector General and Wang Youcai were also happy in the forest for several days. On this day, the two were drinking coconuts, and when they heard the animals talking about electing a new king of the forest, they also followed them to the square, only to see the animals crowding the square.

"Hello everyone, our forest can't be without a king for a day, and today we are looking for everyone in the hope of electing our new king of the forest!" An old antelope stood in the middle of the circle and said, its beard was gray, its voice was vigorous and powerful, and it looked dignified.

"Yes, yes, our great leader has been sacrificed in the battle with the python, and we need to elect a new leader!" Several squirrels said in unison.

"So how to choose?" What are the electoral rules? I want to be the king of the forest too! A fat wild boar raised its nose and shouted.

"Haha, how can the election of the king of the forest be less than me?" I saw a gibbon fall on a large tree fork, shouting loudly. Seeing only one of its ribs, it jumped to the middle of the square.

"Rules, isn't that just to see who has the strength?" The gibbon was so strong that it lifted its thick forelimbs and broke a small branch as it spoke.

Suddenly the animals were talking about it, and it turned out that the gibbon was the king, because it was the most powerful. But since the appearance of the python, the gibbons have fled because they are afraid of the python. At this moment, I heard that the python was dead, and the gibbon was back, wanting to become the king again. The animals did not want gibbons to be elected king, but they did not dare to obstruct.

"The rule this time is no longer to be smarter than strength, but to be smarter than whom, to be better at math than whom!" Because the python was defeated by the mathematical wisdom of the two humans. When the old antelope finished speaking, the animals applauded in agreement.

The gibbons saw that the animals were all in unison, and there was no way, so they had to nod their heads in agreement and say, "I can win better than mathematics, and humans and apes are still close relatives!" ”

"Well, now start raising your hand to register, and those who want to run for office please raise your hand!" The old antelope said.

"There were three people on the scene who raised their hands, namely gibbons, intelligent monkeys and long-tailed foxes. That is, these three people participated in the math competition of the King of the Forest, and two humans came up with the competition questions! A total of three preemptive answers, correct answer plus 1 point, wrong answer deducted one point, the math contest officially began! The old antelope then announced and invited the two men to come forward.

"I feel very honored to be able to give the King of the Forest Math Contest a problem!" Wang Youcai said very excitedly, "The first question is 1+2+3+... 100, add from 1 to 100, what is the result? ”

The scene suddenly fell silent, and gibbons, intelligent monkeys, and long-tailed foxes all meditated.

"It's 5050." Gibbons and intelligent monkeys spoke the answer at the same time.

"The answer is correct! Gibbons and intelligent monkeys each add 1 point, and long-tailed foxes do not. The old antelope announced the results of the first round of competition.

"How did you calculate so fast?" The long-tailed fox said in surprise.

"Hahahahaha, we use the easy method, 1 plus 100 equals 101, 2 plus 99 equals 101, 3 plus 98 equals 101, until 50 plus 51 equals 101, that is, the sum equals 50 101s, that is, 5050!" The clever monkey jumped up happily.

The long-tailed fox sighed and silently left the square, knowing that it could not do it, and gave up the game.

The inspector saw that the first question eliminated one contestant, and not to mention how happy he was, so he continued to ask the second question: "What number is twice equal to the product of this number and itself?" ”

“5。” Gibbons and intelligent monkeys answer at the same time.

The answer was wrong, and one answer was missing, 0. So one point is deducted each, and the two of you are still 0 points! The old antelope announced the answer to the second question.

"Please let me go!" There was a sound from the crowd, and it turned out that the long-tailed fox saw that the gibbon and the intelligent monkey had returned to 0 points, and it came back to continue to compete.

Wang Youcai came up with the third question: "How much does 25 times 64 equal?" ”

“1600。” The clever monkey immediately said the answer.

"The answer is correct, the smart monkey adds 1 point, so the final total score is 1 point for the smart monkey, 1 point for the gibbon, and 0 points for the long-tailed fox!" The old antelope announced the result of the game. The old antelope put the crown on the head of the clever monkey, and the scene was full of jubilation.

"How can you count so fast?" The long-tailed fox asked the clever monkey.

"I used the simple calculation method, because 64 equals 4 times 16, so 25 is multiplied by 64, equal to 25 multiplied by 4 and then multiplied by 16, that is, equal to 100 multiplied by 16, the result is of course 1600!" Smart after said happily.

"Great King, your method is really powerful, and I will ask you for more leave in the future!" The long-tailed fox said.

By this time, the gibbon had already blended into the crowd and fled.
