```Hello Heather,

try:

1 + x^2 /. {x -> 0}

It will give you the 1 you wish.

Best regards,

Betreff: [mg35600] Q: Simplify with "much less" assumptions

Hello, everybody,

I have one question regarding simplify answer with assumptions. For
example, I have "1+x^2". The assumptions is  x is much much less than
1.
Therefore x^2 can be neglected under the above assumption. What I get
after simplification should be "1" only. Can anybody tell me how do
this
in Mathematica? It seems there is no "much less" or "much greater"
symbol in Mathematica. Thank you all.

Heather
