Word Wrapping Mathematical Formulas

There is a prevalent but incorrect belief that mathematical formulas are
images. Many web pages depict them as images. But  mathematical  formulas
are language, albeit 2-dimensional language, but language. Mathematical
symbols are text. Thus a page that allows mathematics to  run off  the
screen should be cited  as an example of  an SC 1.4.10 failure. It is not
an image exception. There are numerous places where line breaks can be
inserted. For example the symbols =, < are > that occur on the main line of
a formula are clear examples. The guide should be that whenever possible a
person should be able to see an entire formula at  400%. Formulas are
difficult enough without having to horizontally scroll to see them. It is
really difficult.
