Over estimation



Hello !!

I am a new user of maxima and it is a great tool, but I have a little 
problem that why i am asking you this question. How can I majorate a 
sum, that is to say : I have :

T = a + b - c + .... - y + z

and I want to majorate the term T with :

maxT = abs(a) + abs(b) + abs(c) ... +abs(y) + abs(z)

maxT will be the sum of absolute values of the initial sum.

Thank you, I hope that my question is quite clear.

Sincerely yours.

Bertrand
