In three minutes a day, you can easily train your brain and feel the infinite charm of a happy life.
Hello everyone, I am a wise life. The early morning brain is the best brain. Then we might as well use this time to do the 24-point math game challenge.
Many people who have left messages recently can easily solve it. It's an exciting thing. Because brain training is so good for us.
First of all, declare
First, the rule is to use addition, subtraction, multiplication, and division, and each number can only be used once.
Second, we must use our minds to make calculations. This is what helps us to train our thinking.
Once you know the rules, it's time for the exciting challenge to begin.
Question 1: 1, 1, 5, 7. The first minute.
The moment these four numbers appeared, I thought that this question would not be difficult. There should also be many ways to do this. Because the numbers are relatively small. We can use multiplication to observe the numbers, and we can see that there are many combinations of 4 and 6, 3 and 8. Then the answer is self-evident.
After my calculations, (7-1) × (5-1) = 24.
I think this question is relatively simple. I wonder how much time everyone spended?
Question 2: 1, 7, 9, 10. The second minute.
At first glance, these four numbers are confusing. However, through careful observation and analysis, it is relatively easy to see the answer. Because the result of the combination of these four numbers is also relatively simple. It took me about 20 seconds to imprint the answer in my head. I think it's still beginner.
Question 3: 1, 6, 11, 13. Last minute.
This question gives a larger number. My first thought was whether I could add them all or use addition and subtraction to equal 24. But this thinking is wrong. If you observe the number 6, but the other three numbers cannot equal 4, then this method is also wrong. So is it possible to use the splitting method to solve the answer? After thinking about it for a long time, I can't solve it. Maybe this question is too difficult for me. There's really no way around it. I've been spending more than a minute on this question, so I'm throwing in the towel. Then I'll consider this question to be advanced.
So I wonder if you can answer the answer? Does it give me a sense of sudden enlightenment?
That's all for today's sharing. Next time, I will definitely work hard and try to solve all the training questions in my own way.
Thank you! I am a wise life, and we will see you next time.
