ALWAYS remember ..
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 don't understand how you find the invariant line.

Another transformation question
3(a)(iv)[2005 June Paper 4(Igcse)]
How do you find the invariant line for the shear?
I actually have this doubt with stretch and shear(finding invariant line), when the image and object share no points.
