If they have showed any interest in math and/or physics, you should consider getting them my MATH&PHYS book: https://www.amazon.com/dp/0992001005/noBSmathphys it's very popular for programmers.

I also have a book on linear algebra, which would be good for people doing more machine learning or data sciency stuff: https://www.amazon.com/dp/0992001021/noBSLA

Both books are perfect for math haters, since they start out with a review of high school math.

This isn't bad. I'm surprised it's expensive now.

The preview is a "special build" of the book that removes most of the content and leaves only the section formulas and headings --- this way to ensure the internal navigation works, but it's confusing since it looks like chunks are missing. Previously I would cut only selected pages but then the links didn't work. Sorry for the confusion. You can check the preview on amazon for the real page numbers: https://www.amazon.com/dp/0992001005/noBSmathphys

I wrote a book that is exactly what you describe (high school math review for adults), which you can check here: https://www.amazon.com/dp/099200103X/noBSmath (~200 pages = compact review of high school math topics with lots of exercises and practice problems)

The green book is a subset of the longer book that also covers mechanics and calculus https://www.amazon.com/dp/0992001005/noBSmathMechCalc (see preview here https://minireference.com/static/excerpts/noBSguide_v5_previ... )

High school math is very deep, so I will not claim to cover all topics, but I present the most useful parts (equations, algebra, functions and inverses, math modelling), so it would be a good starting point.

Independent and in addition to the above, you can check out this printable tutorial on SymPy that can also be helpful as a review of lots of high school math material: https://minireference.com/static/tutorials/sympy_tutorial.pd...

Could have been us — we have a "free PDF if you email me proof of purchase for print" policy for all our books[1,2,3]. Currently, I handle this manually via email, but I wish this was more automated somehow (e.g. shopping cart plugged into print-on-demand fulfillment API + digital delivery of eBook in all formats).

If you're looking for something very basic (high school and calculus), you can check my book No Bullshit Guide to Math & Physics: https://www.amazon.com/dp/0992001005/ Extended preview here: https://minireference.com/static/excerpts/noBSguide_v5_previ...

There is also the No Bullshit Guide to Linear Algebra https://www.amazon.com/dp/0992001021/ Extended preview: https://minireference.com/static/excerpts/noBSguide2LA_previ...

Both come with a review of high school math topics, which may or may not be useful for you, depending on how well you remember the material. Many of the university-level books will assume you know the high school math concepts super well.

One last thing, I highly recommend you try out SymPy which is a computer algebra system that can do a lot of arithmetic and symbolic math operations for you, e.g. simplify expressions, factor polynomials, solve equations, etc. You can try it out without installing anything here https://live.sympy.org/ and this is a short tutorial that explains the basic commands https://minireference.com/static/tutorials/sympy_tutorial.pd...
