Can someone please help me parse this sentence? > Brownian motion and Itô calculare a notable example of fairly high-level mathematics that are applied to model the real world What is “Itô calculare” supposed to have been? I am stumped. “Its calculation”?

Ito calculus - https://en.wikipedia.org/wiki/It%C3%B4_calculus https://en.wikipedia.org/wiki/It%C3%B4_calculus

Itô is the name of the type of calculus (https://en.wikipedia.org/wiki/It%C3%B4_calculus https://en.wikipedia.org/wiki/It%C3%B4_calculus) and calculare I think is just the plural of calculus. So something like "all the itô calculus are notable examples of fairly high level mathematics ..."

  That makes so much more sense! Although the pedant in me wants to argue that calculus plural is “calculi”/“calculuses” (the dictionary gives me the latter, although I’ve never seen it in the wild myself—-but I won’t pursue that because it’s beside the point!) Thanks for the help!

  The plural of calculus is calculi or calculuses. Calculare might be an autocorrection for a different language (https://en.wiktionary.org/wiki/calculare https://en.wiktionary.org/wiki/calculare), though given that the author has a Korean name, it’s more likely just a weird typo.

the article goes into the details in https://jiha-kim.github.io/posts/introduction-to-stochastic-calculus/#the-it%C3%B4-integral-integrating-against-randomness https://jiha-kim.github.io/posts/introduction-to-stochastic-... but the TLDR is it's a way to define integration of random walks.

I think it's a reference to Itô Calculus https://en.wikipedia.org/wiki/It%C3%B4_calculus https://en.wikipedia.org/wiki/It%C3%B4_calculus

It's a typo. "calculare" is supposed to be "calculus are"
