Tips on getting better at math

Yeah I really don't know what to do anymore. I'm going to the 10th grade and I barely understand things like fractions/functions, number lines, I barely know my multiplication and lots more, and I've tried re-learning all of this, I've watched videos I've tried asking for help when it was needed I've done everything people would suggest for you to do. I just hate not understanding simple things about math and having to use google to solve math problems 24/7
