As a developer, this is how I feel when I open a higher math textbook. Even though I understand that, in principle, mathematicians are using a syntax and lingo that shares some common features with computer code, my eyes slide over the words and symbols like they’re a foreign language.
But you are starting at a level that assumes you are no longer a math beginner but rather a beginner in this particular area. If you were reading a high school algebra textbook, you shouldn’t have the same issue.
