Ask HN: Math ability + Coding; can you recommend a resource?

I am starting some elementary coding classes via Udacity etc and have run into some mathematical symbols that are unfamiliar to me. (I never achieved a High School math qualification).

I could simply Google what they are and progress but I am looking to become proficient not just pass tests.

Can anyone recommend a good book/course which will give me a grounding in mathematical concepts relevant to programming before I invest more time in my coding education.

NB : I am not looking to become a coder. I just love learning and enjoy creating things.
