If you need to get into math and are not really motivated I can recommend 3blue1Brown by Grant Sanderson (https://www.3blue1brown.com/). The best part is not only, that he explains math problems in an easy way, but also show how to approach math problems in general. I think it’s one of the best sources to start with Math.

Not sure I’d want to use it as my only resource, but as supplementary material it’s excellent. He really explains concepts well (some better than others though, though this is likely a ymmv issue).

If you are recommending 3B1B from a pov of someone who has already once been past college level math, it's certainly commendable, but does not help someone who has not.
