And, why do think it's bullshit? I don't see anything wrong in the "Vedic Mathematics" book. They are a bunch of mental calculation techniques and tricks. I'd suggest to keep this propaganda propaganda to yourself.

The Quora blog you linked has issues with terminologies and timelines of this specific "Vedic Mathematics" book - such as calling these mental calculation techniques and tricks as Vedic even though there are no references to them in Vedas[2]. This is more of a political matter ;) And, it's already pointed out in the article linked by OP[3]. I'm quoting it here:

It must be pointed out that these sutras given by Tirtha Maharaja are created by the author himself, as stated in the introduction to his book, "Vedic Mathematics" (published posthumously) and are therefore not actually Vedic.

These mathematical sutras are Vedic only in the sense that they are inspired by the Vedas in the mind of one dedicated to the Vedas. Thus the title "Vedic Mathematics" is not correct.

>>>You can also see that the site claims that Jyotish is astronomy but it actually means astrology.

Where? They do mention it as "astrology".

>>>In reality, the scriptures are filled with filth like procedures of sacrificial, bestiality and orgy rituals, calls upon gods to slaughter their enemies (who have stolen their herds), etc.

>>>29. [Saturn] has an emaciated and long physique, has tawny eyes, is windy in temperament, has big teeth, is indolent and lame and has coarse hair.

What is legit or scientific about it?

Have you heard of mythology, euhemerism, and personification? Out of all those stuff on that site, you zeroed-in on sacrificial rituals, description of Saturn, and dismissed everything as "filth"? Then, what is your say on Ganit Shastra, Kaam Shastra, Khagol Shastra to name a few?

Based on that logic, all these below must be filth and their sole purpose is to brainwash people:
