Vedic-matrix is an ancient Indian number-applying knowledge. It is a 2D-square-matrix having a-unit-merged rows and equal-number 'a-unit merged columns starting from left top far corner origin of matrix!

A 2D square matrix 0…9 is given below. Either Matrix 0...9, or 00...99 or a higher order consistently relates Vedic-sutras given in "Vedic Mathematics". Vedic-matrix is therefore a tool (for all people) to mentally relate Vedic computing! Why Vedic-matrix is a bit unnatural and manner to relate matrix to Vedic computing is subject matter!

Start-'row(y) and column(x)' of matrix merges at left top corner that instantly relate position-sense of 'all remaining 'yx' origins of matrix.
Merged left top corner origin is 00 and '01, 02, 03, 04, 05, 06, 07, 08 and 09' increase towards right by a-unit in a usual read/write order. Said a-unit increase continues (in page read order) up to last origin!
