Impatience. Math takes a lot of time. Other subjects, it's a simple answer. Like psychology, history, English, etc. You just mainly just memorize text. Math, you actually have to solve.
Why do some people hate math?
The simple answer.... Cos they don't understand it.
It's a very hard subject.
Impatience and our fast food, disposable lifestyle. People don't like having to work so hard.
I had a teacher once who told me that when it comes to math and science our brains are a muscle. The more you exercise it the stronger it would be. So, maybe in the first week I wasn't that fabulous, but the more I worked on it the easier it came for me. It was so true. Understanding that made a huge difference in my life. I no longer berated myself for not "getting it". It just took time and mental math/science exercise.
I think all to often it is taught only one way, and not everyone thinks that way, making it difficult for many to understand. I happen to catch on quickly with math and I usually quit listening to the teacher trying to explain concepts to people as it just confused me. I think if we had smaller classrooms where there are less students teachers can better give each student the time and explanation they need to understand their lessons.
because it is really really hard.
I think a lot of it comes down to teachers and the way it is taught. Never really made much sense in high school, but I squeaked thru. Twenty years later went back to college algebra to stretch my mind. Teacher was amazing. Had I had him in hifgh school, I might have actually gone into engineering.
Probably for the same reason I dislike English literature--- weird (technical type) concepts like iambic pentameter that I will never use in the future and a disproportionate amount of my high school time "wasted" in gaining sufficient proficiency in the subject to pass with a decent grade.
