If you try your best to like math, and you don't like it. You are just learning math the wrong way. The same goes for any subject.
What is although true, is that liking a subject means you've found the best learning method for that subject.
If you have found the best learning method for the subject, for yourself; and yet you are shitty at the subject, the subject is not for you.
I used to hate math and I did bad at it, but now I like math and I'm one of the top students in my class for advanced placement advanced functions even though I'm in gr 11.
The reason I started liking math is because I started to try and understand every single concept I worked with, rather than remember the process of solving a problem. Because I understood the problem, just like I understand that I will fall back down when I jump, I was able to work with problems without a formula.
Math works in a way where you have to break it down to its fundamental level to be truly good at it. I know a lot of people in my class who are only "good" at math because they can memorise well, and the only reason they like it is because of the marks and grades which is stupid.
The best step before learning math, is to figure out what is the best way to learn math that makes you enjoy it.
Another key factor is get the school textbook that the math teacher hands out to his/her students. The teacher will DEFINITELY use questions and concepts from the school textbook on examinations.
Since your concentration is low, you will want to do textbook questions that are relevant to what is being taught, so I'd recommend asking your teacher for a syllabus a.k.a what is for homework for all the math units that they teach in class, and doing those questions.
If your teacher has shit to say about taking home a textbook, then deposit a fee amounting to the cost of the textbook at the school, and collect the cheque once you give back the textbook.
