Hi. I'm dependent on a package that is dependent on math-expressions. Can this PR be merged? Thanks!

I'll have to look more into this. Just upgrading mathjs to 7.5.1 breaks most of the tests, so need to figure out how to deal with the breaking changes. I'm unable to do this right away, but hope to take a look in July.

[dependabot]

Looks like mathjs is up-to-date now, so this is no longer needed.
