We have the equations:
1 z 2 x = 5 (1)
3 x 2 y = 1 (2)
1 z 1 y = 5 (3)

Subtract equation (3) from equation (1)
1 z 2 x 1 z + 1 y = 5 5
2 x + 1 y = 0
1 y = 2 x (4)

Now, put this value in equation (2)
3 x 4 x = 1
1 x = 1
x = 1

Put x = 1 in equation (4)
1 y = 2 1
y = 1 2

Now, put x = 1 in equation (1)
1 z + 2 = 5
1 z = 3
z = 1 3
{ x = 1 y = 1 2 z = 1 3

I can understand the logic behinde α 0 = 1 butthen out of no where α 1 n = a n "becauseit just so happenes that way"(they say) without any realexplanation to why its so. Can someone provide me with the logicbehind this statment.
PS: To learn math is memoization but to understand it isintuition from the mind.
