Hope this is the right place to post this.

I am a 30 year old woman with a third grader and really realizing how much my school system failed me. I honestly don't understand anything past simple multiplication and division. I want to learn honestly more for myself than necessarily helping her with homework. But are they're any books for completely relearning Math. Should I just go get 3rd grade work books and start there? I don't think YouTube videos will be helpful for my brain at the moment.
