Check out this short excerpt of definitions and examples of the math "alien symbols": https://minireference.com/static/excerpts/set_notation.pdf https://minireference.com/static/excerpts/set_notation.pdf They are really not that bad once you learn their meaning + very useful shorthand (you can think of math notation as a DSL with specific expressions for math operations). Longer preview of the book: https://minireference.com/static/excerpts/noBSguide_v5_preview.pdf https://minireference.com/static/excerpts/noBSguide_v5_previ... and here is another preview of the LA book: https://minireference.com/static/excerpts/noBSguide2LA_preview.pdf https://minireference.com/static/excerpts/noBSguide2LA_previ... Both books have been pretty popular with the programming crowd. They use standard math notation, but there are lots of code examples and computing analogies, so you'll feel right at home.
