Excuse the bad format=able2know format isn't compatible
y=mx+b

[9 1][m] [7]
[5 1]=[2]

[m] [9 1]^-1[7]
=[5 1] [2]

[9 1]^-1 [ 1 -1]
[5 1] =1/4[-5 9]

[m] [ 5]
=1/4[-17]

y=1/4(5x-17)

Check
y0=1/4(5*9-17)=1/4(45-17)=1/4*28=7
y1=1/4(5*5-17)=1/4(25-17)=1/4*8=2

OK

Rap

I get the distinct impression that no one is interested. What do you think Quehoniaomath?

Why do I suddenly have a headache? I was fine until I started reading this thread.

(3x+4) / (6x+7) = (x+1) / (2x+3)

Vedic Math is solving with pleasure not with pressure.

No it's not.

There is a worldwide debate currently raging about the efficacy
of Vedic mathematics versus the crumbling foundations of
Western mathematics. Generally speaking, the theorems we all
learned at school are not wrong, but clumsy. Some of the Western
geometrical formulas are certainly inadequate. For example, the
formulas for sphere packing in the higher dimensions increase up
to the sixth dimension, then suddenly decrease for higher dimensions,
which is simply absurd.
Unfortunately, some diehard senior mathematicians, in an
attempt to protect the crumbling foundations that they now stand
on, feel threatened by the lightning-quick mental calculations of
Vedic mathematicians and go to great lengths to deride Vedic
maths as a "bag of tricks".

Is there also a "worldwide debate" about whether jet engines work?

You never cease to crack me up.

It is a single crackpot book that has gained a small following on the internet.

I work in Information Technology. We use real math. No one cares about crackpot math tricks.

Vedic Mathematics s so good that it is even used in the field of
Information Technology!
