Three weaknesses in math could be inadequate understanding of fundamental concepts, difficulty in problemsolving, and lack of attention to detail.
And now, more specifically
When it comes to weaknesses in math, there are a few common ones that many people struggle with. Here are three of the most prevalent:

Inadequate understanding of fundamental concepts. This is perhaps the most significant weakness in math, as without a solid grounding in core concepts, it is difficult to progress in the subject. As Dr. Jo Boaler, a professor of mathematics education at Stanford University, explains, “In mathematics, the most important thing is to develop a deep understanding of concepts and procedures, rather than just memorizing them.” In other words, it’s not enough to simply know how to perform certain operations – you need to understand why they work, and how they relate to other mathematical concepts.

Difficulty in problemsolving. Mathematics is often described as a language of problemsolving, which means that being able to tackle challenging problems is a crucial skill. However, many people struggle with this aspect of math. One reason for this may be that they focus too much on finding a specific answer, rather than on the process of getting there. As math educator Marilyn Burns notes, “The most important goal of problemsolving is not to find a solution, but to develop the problemsolving skills that will help you solve other problems in the future.”

Lack of attention to detail. Despite its reputation for being a purely logical and rational subject, math actually requires a great deal of attention to detail. From keeping track of signs and symbols to remembering formulas, there are countless details that can trip up even the most knowledgeable math student. As mathematician Paul Halmos once said, “The only way to learn mathematics is to do mathematics,” and this means being willing to put in the time and effort required to develop a strong attention to detail.
Interesting facts about math:
 The word “mathematics” comes from the Greek word μάθημα (mathēma), which means “knowledge”, “study”, or “learning”.
 According to a 2019 study, only 36% of Americans can name a single living mathematician. Mathematicians are often overlooked and underappreciated, despite the fact that their work shapes our understanding of the world around us.
 The concept of zero was first developed in India over 1500 years ago, and was essential to the development of modern mathematics.
 Some of the most famous unsolved problems in mathematics include the Riemann hypothesis, the P vs. NP problem, and the Birch and SwinnertonDyer conjecture.
 Math anxiety is a real phenomenon that affects many people, and can be a significant barrier to learning math. According to a 2020 study, around 20% of American adults experience high levels of math anxiety.

A video response to “What are three weaknesses in math?”
This part of the video discusses the weakness of mathematics, specifically the fact that axioms are unprovable and must be accepted as they are. Despite the lack of reallife applications for nonEuclidean geometry, mathematics remains popular due to its intuitive correctness and practical applicability. The video then raises the question of whether religious belief can also be based on a logical construction built upon unprovable but intuitively correct propositions and suggests an axiomatic system for religious faith in the next episode.
On the Internet, there are additional viewpoints
Mistakes such as number additions, substitutions, transpositions, omissions, and reversals in writing, reading, and recalling numbers. Difficulty with abstract concepts of time and direction. Inability to recall schedules and sequences of past or future events. Being chronically early or late.
I will be honest, I do not like how society has made it seem that there are math people and nonmath people. It is like any other skill, you have to put in the time, and eventually you will become better.
There are certainly ways to improve mathematical ability though. What it will really take is a lot of time in understanding your flaws. For instance, when you take a multiple choice test in math, there is a chance that you may get the answer right by guessing. But even if you got the answer right, that does not mean that you understood how to do it. So along with the answers that you get wrong, you need to also analyse what you got right.
If you go over your work, and still can not figure out the error in your ways, you should always ask for help. I find that most people know more than they think they do. I remember I was helping out a BC Calc student who made a 33 on one of his tests. But when I went over it wit him, he actually knew a lot more than that, he just did not do well be…
