Generally speaking, doing things in algorithm requires programmers to have higher requirements in mathematics; However, if you are an ordinary programmer, the requirements for mathematics are actually not that high. Many junior and senior high school students can learn 0-based development and become programmers in the future. Moreover, knowledge points such as variables are relatively simple and do not involve too deep mathematics. So, I think maybe you don't have a good knowledge of variables. Learning development and learning methods are also very important, which can be communicated privately. In addition, you will always encounter various problems in your study. No matter what you learn, you should keep your mind at peace and don't collapse. It's easy to give up, but only by persistence can you become an excellent programmer. Come on!
