    Certainly, many of these are 'tricks' used by 'memory' artists,
    (I accept 'tricks' is not the correct expression)

    Take a look at:

    Take notice of tutorial 4 which indicates any number ending in 5 (eg 25)
    can be squared by taking the 5 and squaring it = 25 and then taking the remaining value and multiplying it by (itself+1) ie 2*3 = 6 put the results together = 625 ie multiply the 6 by 100. It is correct and always works, here is the proof which I used many years ago to check it's validity for myself.

    Now pick a number (ending in 5) say 135

    Let n=13 then 135^2 = (10n+5)^2 = 100n^2 + 100n + 25 = x [eq1]

    Now equate vedic to a normal equation for this example gives:

    x = (n * (n+1) * 100 ) + 25 (The 100 comes from 'shifting past 25')

    = 100n (n+1) + 25 = 100n^2 + 100n + 25 ie the same as eq[1]

    I frequently use 'vedic' but ONLY where I have proven to myself it is valid.
    I have never come across a Vedic which does NOT conform to 'conventional maths' I have NOT tested them all.
