Problem displaying the formula

[saraOrkide]

The displayed formula is not the same as what was typed in the Word environment

In the word file it is like this:

But when it is converted from word to mml, it is displayed like this:

As you can see, the formula should have gone to the next line, but it didn't

MathJax's rendering is correct for the MathML that you have supplied. Three mtable elements in a row, with no intervening elements, as in your second and third expressions, should be rendered horizontally as MathJax does. As these fall within a single inline math element, there are no valid in-line breakpoints for MathJax's in-line breaking algorithm. It may be that Word allows line breaks at these points (the MathML specification does not specify an in-line breaking algorithm).

You probably want to combine the three separate mtable elements into a single table, as in your first expression. For example:

Note that I've also removed the accentunder="false" attributes, which are not what you want, here. The underprices are accents, and want to be rendered at the same size as the expression they are under, not at a reduced size (as non-accents are), and accents get placed closer to the material they are under (or over), rather than on a separate baseline as non-accents are.

An alternative would be to place <mo linebreak="newline"></mo> between the tables, but the spacing between the lines will not be as good.

I'm sorry, I had sent the mml for only one mtable
