The UNICODE glyphs we'd need for these as drawn from OpenSymbol are

CIRCLED PLUS -- U+2295  // ⊕
CIRCLED MINUS -- U+2296 // ⊖
CIRCLED TIMES -- U+2297 // ⊗
CIRCLED DIVISION SLASH -- U+2298 // ⊘
CIRCLED DOT OPERATOR -- U+2299 // ⊙

Those are fine...

But suggest you should compare each of the Elements panels from a Math Formula
editor session to the current "new" Help articles from comment 1 for the glyphs
you'll need (looking at both the PNG images, or when just entered as starmath). 

Then look for the glyph in OpenSymbol, using the LibreOffice Special Characters
dialog, or another chart based font utility (I prefer BableMap [1] on Windows).

That would allow you to identify most things needing an SVG for the new Help,
but suspect there will be a few that can't be done with just the font glyphs
and line work.
