I am a mathematics graduate student and am currently writing a cover letter. The main reason I decided to study mathematics (bachelor back then), was because I found mathematics really difficult. If I was going to spend three years in college, I wanted to challenge and improve myself.

Is there a word or phrase to describe something that was once difficult but now easy? The best thing I could come up with was "I have grown accustomed to" but this does not represent the effort I put into mastering math nor does it describe I now actually do find it easy.

  • Avoid word/phrase requests that lack: (i) objective criteria for accepting answers, including connotation, register, and part of speech; (ii) exact context – generally we want the sentence you’re writing; and (iii) details of research you’ve already done (trips to the thesaurus, etc.) including solutions you’ve already rejected, and why.

  • What is missing from your use of "mastering math" ? To master implies working hard and that the practice is no longer a struggle (easy ?) .. if you're looking for the 'thing' you've mastered, would a field have a nature itself ? topic, discipline, art, subject etc? Why would a field have a trait relating to it's past and pretense to a person – Tom22 May 15 '18 at 21:17

    The once-difficult subject has become second nature. – Xanne May 16 '18 at 3:28

  • It was difficult to master. To master something implies that it is now easy to perform. – Jason Bassford May 16 '18 at 15:56
