The MathML line-breaking algorithm only allows breaks to happen at <mo> or <mspace> elements and MathJax follows this (since, as mentioned, it's a MathML renderer at heart). Spacing around operators and relations in math mode are governed by specific skip widths: \thinmuskip (by default it is equal to 3 mu) \medmuskip (by default it is equal to 4 mu) \thickmuskip (by default it is equal to 5 mu) \begin{ align* } 3ax+4by=5cz \\ 3ax<4by+5cz \end{ align* } Open this example in Overleaf.
