Math Journey Log

Read about the entire math career of DeGatchi!




  • Smashing through “Linear algebra done right”. Actually doing all the exercises and learning a lot from the failures. Failing truly is the fastest way to learn because you’re correcting your mistakes and updating your mental model. How can you verify your mental model if you never apply it? You will assume it always right :)
  • Actually understanding fractions now — might do a quick article for them. Math is all about what can you add to your toolbox.
  • Understanding matrix multiplication super well — wrote about it in one of my blogs.
  • Learned about sigma notation.



  • ”Proofs explain why mathematics works and not just how”, from p108 in “Linear Algebra Step By Step”.
