Hi Everyone
I am a new contributor.I just explored the SymPy project a bit and the idea
really fascinates me. I would like to contribute to the project. Please
guide me about making contributions in the project .
Thank you :-)

Cancellation of removable singularities is useful enough that it's
included in the default simplify() heuristics. Without it, it would be
quite annoying to most use cases. It's also not uncommon that in the
process of creating an expression a removable singularity is created,
through multiplying an
ConditionSet no. Sets are not the same thing as booleans. A set is a
collection of objects. A boolean should be replaceable with true or
false. ConditionSet(x, x > 1, {1, 2, 3}) is the same thing as {2, 3},

from booleans and visa v
