To solve math problems well, you need mathematical thinking and problem-solving skills.
Did you know that the more you think about it, the bigger your tree of thoughts becomes?
If you already have good thinking skills and know how to take a variety of approaches,
you are probably already good at math.
However, people who have difficulty with math or young students
who are just beginning to learn math need training in thinking and creativity.
Of course, it is also good for those who like brain training or those who need to continue training their creativity.
I planned and uploaded a math puzzle that most people fail at, as well as an easier matchstick problem.
Today, rather than simply posting the matchstick problem and showing its correct answer,
I'm going to talk about the approach.
First, I will explain by looking at the basic questions.
The most basic problems involve changing numbers.
Most of the time, only one moves.
Let's look at the problem.
The point of this problem is that 9 and 0 are the same number of matchsticks.
Just change 9+9=9 to 0+9=9 or 9+0=9.
When the basic matchstick numbers are the same,
there are times when you change them within them,
and there are times when you change the numbers by bringing them from somewhere else.
The third method is fun because it is creative. Think about it.
You will naturally find the answer as you watch the video or read the article.
In most matchstick equation problems, there is a precondition that the equal sign is not touched.
If it doesn't say that and you don't know,
just remove the matchstick from the 9 and change the equal sign to not equal.
Then you can guess it even if you don't know much.
There are three ways to do this without changing the equal sign.
Of course there could be more.
First, change the number!!
Change the 2 in front to 9. 9-5=4
If you are good at changing numbers, you can solve most matchstick equation problems.
The second and third methods are to start by replacing subtraction with addition.
2+2=4 And another way!
Because they can think in such diverse ways,
I think doing matchstick puzzles like this from a young age
is very helpful to children and students.
When I was young, my math skills improved after reading a book called ‘Building a Brain’.
If you naturally access such puzzle books or videos with your family,
your family's thinking skills and creativity can improve.
When I teach many students, there are some who I feel most sorry for.
Solving a large number of workbooks does not guarantee good math grades,
but when students do not get good grades,
they continue to work harder and increase the amount of problem solving they do.
Mathematics should develop your ability to think. You have to think about different things.
Oh! Professional spirit!
The nagging got longer without me even realizing it. Let's go back to the explanation.
First, we look at the problem and try to change the numbers.
But no matter what you do, it doesn't work.
Then, the approach is to change subtraction into addition and addition into subtraction.
Subtract one from 9 and get 2+3=5
oh! Finally, it was time for the tickets to come out.
First, add, subtract, multiply, and divide.
It would be good to know how many matchsticks you need.
Usually, 7 is written using four matchsticks, but depending on the test taker, three matchsticks are also used.
From here, we learn that the intention of the test taker is important.
When solving high school math, the test taker's intention and clues are very important,
and the matchstick problem was the same.
To explain briefly with an example:
Since 9 and 5 are one difference, and subtraction and addition are also one difference,
we can change 9 to 5 and subtraction to addition.
And 4 and 7 require the same number of matchsticks, so if you lift them up, they become 7!
You can change it to 2+5=7.
The problem that uses the relationship between 6, 9, and 0 is the problem we first saw.
The ideal thing is to make various moves and think about it every time without looking at the table.
However, for children who do not have much thinking power at first,
looking at the table can be one way to solve problems.
Creating a table yourself and understanding the test taker's intention by looking at it
will be very helpful in improving your math skills and thinking power.
One of the most important things to do when solving difficult math problems is to eliminate preconceptions.
Matchstick equation problems eliminate these preconceptions and train you to think differently.
Through shape problems like this, you can become familiar with squares and equilateral triangles.
Lastly, here is a link to a YouTube video that comprehensively summarizes the matchstick problem.
