This problem requires us to move a matchstick to make the equation hold. First, we observe the equation:1+1+21+12 = 44. We can find that the left side of the equation can be divided into two parts:1+1and 2 1+ 12. If we move a matchstick so that the first part on the left side of the equation becomes 20, then the equation will become: 20+2 1+ 12=53.
However, this is not equal to the number 44 on the right side of the equation. Therefore, we need to continue to find other solutions. If we move a matchstick so that the second part on the left side of the equation becomes 22, then the equation becomes:1+1+22+12 = 46, which is still not equal to the number 44 on the right side of the equation. Therefore, we need to try other solutions.
If we move a matchstick so that the number on the right side of the equation becomes 33, then the equation becomes1+11+21+33 = 66. Therefore, both sides of the equation become 66, and the equation holds. So, the correct answer is: change the number 44 on the right side of the equation to 33.
In addition to the application in disciplines, mathematics is also widely used in our daily life. For example, calculating the price when shopping, calculating the distance when traveling and calculating the area in architectural design all require mathematical knowledge. In addition, mathematics is also widely used in data analysis, artificial intelligence and other fields, which brings convenience and progress to our lives.
In a word, mathematics is a very important subject, which is not only widely used in various disciplines, but also ubiquitous in our daily life. By studying mathematics, we can better understand natural phenomena and social laws, better solve practical problems and better explore unknown fields.
At the same time, learning mathematics can also cultivate our logical thinking and abstract thinking ability and improve our creativity and innovation ability. Therefore, we should attach importance to the research and application of mathematics and make contributions to the progress and development of mankind.
