Tatyana Chernigovskaya, Ph.D., says that educational math lessons are vital for all people. Mathematics is a science that teaches children not only to add 2 + 2. When solving mathematical problems, neural connections appear in our brains that allow us to make correct decisions and analyze complex situations.
It’s not just kids who need to train their brains by solving math problems. This is especially important for adults and the elderly. Mathematics allows you to keep your mind clear longer and develops your memory. If you solve a few simple math problems every day, after a month you will be able to go to the store without a shopping list. After all, our brain is a unique structure. The more you strain your brain, the sharper your thinking will be.
Today we invite you to solve one simple mathematical puzzle. This task caused a serious scandal on Twitter. Thousands of people argue over which answer is correct. We invite you to join this discussion and submit your answer. Even if your answer will be wrong, the important thing is that your brain has already started active. Try not to use your phone or other electronic devices.
Look at this problem carefully. Only at first glance it seems complicated. If you remember the simple rules of priority in mathematical problems, you will not have any difficulties. Now that you have managed to solve this problem on your own, let’s check if your answer is correct. We will start with a rule that has been established by mathematicians from different countries. They agreed on the priority of solving tasks with different signs. So the first thing we do is the expression inside the parentheses if they are in the problem. There are no parentheses in our problem, so let’s move on to the second part of the rule. Multiplication and division take precedence over addition and subtraction.
So, first we multiply 1 by 0 and divide 2 by 2. The result is: 6 – 0 + 1. Now everything is very clear and simple. The correct answer is seven. You can double check using the calculator on your phone. There is a priority rule in the phone calculator settings. So, your phone’s calculator will immediately give you the correct answer.
On our website you will find many similar tasks that will help you exercise your brain. Invite your family members to solve some problems together and discuss the results. This way of spending time will not only bring your family closer, but also strengthen the neural connections of the brain. Children will find it much more interesting to solve problems at school when they see adults solving mathematical problems in everyday life. Write in the comments if you managed to get the correct answer.
