for addition and multiplication ..

LB = LB + LB

LB = LB x LB

UB = UB + UB

UB = UB x UB

for subtraction or division .. (is different)
LB = LB - UB

LB = LB/UB

UB = UB - LB

UB = UB/LB  :)

consider solving some sums u'll get them  :).. these kinda ques usually appear in paper 2 .. (jus solved a couple of them few mins ago)

I dont really get it. If you would solve me some questions from the past papers with the formula's you provided, it would be really helpful.

Fastal:
i know its perpendicular to the invariant line, but how far away from the base is it?

lets say "_" got stretched, and the image also moved away, in this case where is the invariant line?-------

Ghost Of Highbury:
The base didn't change its shape. Thus, the x-axis is invariant.
