the same way you git gud at anything:
practice.

my guess is that you never will, since you're spending time asking /sci/entologists how to get good at math rather than actually practicing math.

i think i'm only barely decent at math, and I do it for about 2-4 hours a day. i would probably be a lot better if I did it for 6-8 hours or more.

you want to get good at anything? the answer is to just do it a lot

>Actually do math. (your picture says it anon.)
>Read up on mental math.
>Watch this(with an open mind). It's impressive when you can make quick estimations and it gives you better number sense if you practice it. (really!)

What use is being an arithmetic ninjas? Numbers are useless distinctions of reality. Relationships are the only important conclusion to be made from mathematics.
