Linear Algebra : Machine Learning, Computer Graphics, Computational Geometry, etc.
Number Theory : Cryptography.
'Calculus 1' : Useful to know for 'maturity', you will likely not use it unless you implement numerical algorithm libraries.
Probability / Statistics : Heavily in Machine Learning and related fields, in small doses everywhere else just because you need to be able to create useful observations and presentations.
I would add another branch:
Logic : If you work with programming languages or verification.
Discrete Maths / Combinatorics : Probably everywhere.
