** **56. "General Case Integer Subtraction"

by Chard Aye R. Alova, 2021

With the system of Vedic Mathematics, subtraction can be done with a much simpler,

easier, and more creative method which can change the way pupils see subtraction as a

fundamental operation in Arithmetic and in the whole of Mathematics.

This paper shows the firepower of the sutras All from Nine and the Last from Ten for the General

Case Arithmetic Subtraction, and with the help of the sutra Transpose and Apply for the General Case Integer Subtraction.
