how to make a new line in a jupyter markdown cell

Question

md $S$: a set of shops $I$: a set of items M wants to get

I\'d like to make a new line between this two sentences. We usually put \" (space)\" after the fi

Answer 1

"We usually put ' (space)' after the first sentence before a new line, but it doesn't work in Jupyter."

That inspired me to try using two spaces instead of just one - and it worked!!

(Of course, that functionality could possibly have been introduced between when the question was asked in January 2017, and when my answer was posted in March 2018.)
