Well on some contexts maths is apart from science, see e.g. the STEM acronym :)

People generally consider, although this is not universally agreed, that math isn't science. To me the distinction matters, although it's fairly subtle.

This is underscored by frequently cited articles, like: "The Unreasonable Effectiveness of Mathematics in the Natural Sciences", in which math is treated as separate, but intimately related, to natural philosophy.

I think you can do math without science, but you can't do science without math.
