No one is bad at mathematics. You can’t be bad at mathematics because it is logically defined with rules. All you have to do is follow rules, so anyone can do it. You can only be bad at things like art, singing, writing. Those things take talent and are not defined by rules. Some people have talent for mathematics which helps, but it is not a prerequisite.

The problem with mathematics is they teach you “how” you do things but not “why” you do things. Thats why so many people like liked it, including me at one time. After you understand the “why”, the “how” falls in place and mathematics flows like a language. You still should do things over and over but you wouldn’t have to repeat it as many times.
