How to Stop Making Stupid Mistakes on Math

Initially relaxed, you get back your math test but there are red marks on the page. You are shocked because you didn't expect to lose points on the easiest parts of the test. How often does that happen to you? If this is not unusual, then this article is probably very helpful for you. Careless mistakes on math tests result in losing a few points, which may ultimately put a student's grade on the border between an A and an A-. What was said previously may have been an exaggeration, but these small actions may have a big impact on a student's grades or score on a standardized test. Without further ado, the process used to prevent making careless mistakes will be revealed. The process doesn't guarantee all the future careless mistakes will be eliminated. However, the process will lessen the chance of careless mistakes to occur by a substantial amount. Using this method ever since high school has really helped me notice what I did wrong on math tests before time is called.
The method I use is the numbered box method. This method is not created out of my own imagination; in fact, the numbered box method was mentioned in a popular Art of Problem Solving article. My article will be different from the one on AOPS as I will include other details.
Before I start the numbered box method, I read the question carefully line by line and circle or underline what I am being asked. Reading the question carefully is pretty crucial on SAT math because they ask you very specific values. I may need to write down briefly what is the concept that is being tested. Then, I write down equations that are related to the concept. Writing down formulas are pretty helpful because it prevents you from doing mental math. For visual math problems, drawing a graph or picture is highly recommend because it isn't good to do all the thinking in the brain.
In the numbered box method, you number the steps for solving a problem with a brief description in 1-3 words about the step. Then, write neatly line by line for solving the problem that involves calculations. When you complete the first step, you should box the first step and then make a new box for your second step. Keep doing this until you finished the math problem. Although it may sound tedious to box your work and write the steps, I find it to be a very good way of organizing your work and forcing yourself to not have messy handwriting. If I write messy, the xs look like ys, and then the 0s look like 9s. Another important thing about handwriting is to not have small handwriting that is crammed together. Maybe I am wrong (as I cannot speak on behalf for people with small handwriting), but I think spacing out your work really helps see things more clearly.
Here is an example of using numbered box method:

While doing your calculations or arithmetic, you cannot skip steps and do mental math. I have tried that many times and learned that it is kind of risky because you end up making some stupid mistake. For instance, I suddenly realized while double checking I made a calculation mistake because I thought n*0=n. Why did this happen? Because I did not write it down on paper! Another good habit while you are doing the steps is internally talking about how to solve a problem as if you were a teacher. I don't really do this all the time, but lecturing it in your head makes you be more aware of each step.
For double checking, I personally find it ineffective to simply stare at your paper until time is called. You are not actively checking. What you are doing is passively checking. Again, my steps sound like I waste a lot of time, but here's the paradox: the best way to be fast is to not be fast. What do I mean by this? What I mean is that when you are thorough and meticulous, you avoid a lot of potential careless mistakes, so you don't have to waste time resolving the whole thing from the start. If you have enough time, double check by repeating the process that I described above. Reread the question carefully, do the numbered box method, and see if your answer matches the previous one.
In a nutshell, one method of performing better on math tests is changing your approach to the tests and establishing a good work habit.

My Accepted BU RISE Essays

BU RISE is a 6-week research program at Boston University. In 2019, the acceptance rate was around 16% so it is a selective program. There are two tracks- internship and practicum. The internship is the one I applied to because I wanted to work in a lab. Unfortunately, BU RISE in 2020 was cancelled due to COVID-19. If you are applying to BU RISE, these essays may be a source of inspiration.  1.Why you selected your field of interest and what you would like to research (300 words)  First choice: medical laboratory research (biochemistry) Second choice: chemistry  Ever since 2018, I participated in a Science Olympiad event called Protein Modeling that sparked my interest in proteins. When I learned about the anti-CRISPR protein, it alarmed me that the protein stopped CRISPR from working. Wondering how this could happen, I used Jmol to build and visualize the protein model. Over time, I no longer viewed proteins as messy globs. Instead, I appreciated that the protein’s disti...

The Funny Thing About Memory

 The more I stay in the U.S., the more I remember my years in Taiwan in a positive light. I feel like my nostalgia for Taiwan caused my memories to become distorted. When I lived in Taiwan, I disliked the humid environment and the gray skies after rainy days. I complained that the buildings had gray walls from the mold that grew on them. In elementary school, I wished that the city planning reflected the U.S. system where all the residential buildings were together instead of having commercial and residential buildings next to each other. After returning to the U.S. five years later, however, I don't really think those aspects of Taiwan were really downsides. Nowadays, I somehow manage to neglect those "downsides" whenever I think of Taiwan.  What I currently think about Taiwan is not what I expected to reflect upon the most as I boarded the plane to San Francisco in 2016. When I saw the green land vanish before my eyes outside my airplane window, I thought about how much...

Why I Blog

 For the past two years, I have been blogging every so often, but I never asked myself why I blogged. The main reason I blog is to store and organize my thoughts that I keep hearing in my brain. These thoughts range from past memories to feelings of disappointment or anger. By writing my thoughts, I gain some clarity. Also, blogging serves as a form of self-reflection that I need to do on a regular basis or else my brain still acts fuzzy.  Although I write a lot of posts that aren't positive, I have a pretty good life. The reason that I tend to write a lot of negative things about myself on the blog is that if I don't write about bad things, then they keep bothering me. Worse, I may not learn from my mistakes or lessons. Still, I will try to balance out the negative content with some positive content because I want this blog to be useful for others. I don't want a blog where I all I do is criticize myself for failing to live up to my expectations. Instead, I want this websi...
