Not always "{} newline {}". You use {} when you need to provide the
missing operand of a binary operator. For example,
a+b_ij newline = c+d # left-hand side is missing at the second line
a+b_ij newline {} = c+d # add {} - OK
a+b_ij = newline c+d # right-hand side is missing at the first line
a+b_ij = {} newline = c+d # add {} - OK
And from my point of view, the requirement - "provide all operands,
otherwise there will be the flipped question mark" - is simply awful, it
would be a great improvement to get rid of it. newline's behavior will
be much more intuitive.

Title:
[Upstream] Math equation editor: "newline" fails after symbols

3) What is expected to happen in LibreOffice Writer via the Terminal:
cd ~/Desktop && wget
https://bugs.launchpad.net/ubuntu/+source/libreoffice/+bug/281053/+attachment/2417117/+files/math_newline_issue.tar.gz
&& file-roller -h math_newline_issue.tar.gz && cd math_newline_issue
&& lowriter -nologo math_newline_issue.odt
is no upside down question marks are presented in the Math formulas.
4) What happens is the upside down question marks are present
erroneously due to "newline" command. If "newline" is preceded or
followed by some characters (as +, -, =, which are often needed), some
error marks "¿" are obtained, and perhaps only a single line if
displayed (it depends on the character and its relative position to
"newline"). Examples :
a+b_ij = newline = c+d # single line; error mark
a+b_ij newline = c+d # two lines; missing "="; error mark
a+b_ij newline + c+d # correct behaviour !! The "+" sign does fine
after newline...
a+b_ij + newline c+d # ... but not before: single line, error mark here
a+b_ij = newline c+d # single line, error mark. The "=" sign does bad
whether after or before newline
WORKAROUND: {} newline {}
