[Tugindia] different shaped brackets

[David Owen]

Dear Everyone,
I have a little problem:
Is it a good typing style to always have DIFFERENT shaped brackets in
mathematical equations involving several bracketed expressions? For example,
is good to write:
1)    ( {[a+b+c](g-p)}+j)(d-n+x) = y

or

2)  ( ((a+b+c)(g-p))+j)(d-n+x) = y, where some brackets may be larger than
others?

That is, is it a good style to mix the brackets or to use one type of
bracket, some of which may be larger than others?
Thanking you all,
D.O.
