Since most functions defined by symbolic expressions hardcode the type of the result as `sage.symbolic.expression.Expression`, it is not possible to inherit from the `Expression` class.

It should be possible to dump any state to a file in order to resume it later or ship it to a different machine.
One option is to extend QEMU's snapshot mechanism to save symbolic data and constrai…

# Description
Many early prominent mutlibody dynamics codes use computer algebra systems (CAS) to symbolically derive long form analytic expressions for the equations of motion of the system. Most …

The following algebraic number is clearly real, but the AA class seems to have trouble digesting it:

Same symbolic expressions written in form of add and mul are not equated as equal.
For instance:
```
r1 = add(im2, mul(i2, x));
r2 = mul(i2, add(im1, x));
assert(eq(r1, r2));
```
fails. …

In my recent research, I used pysr to do some symbolic regression tasks. I found that pysr 's loss is even smaller than ANN in some cases. How can I explain this magic of pysr ? Why is the res…

using `OrderedDict` as a substitution rule fails to unpack composite expressions (`Pow`, `Mul`, `Add`, `Div`)

For instance, why is `powsimp()` a function and a method for (at least most) symbolic expressions, but `expand_power_exp()` is only a function? I often find myself "stabbing" at methods only to learn …

Does it make sense for these to have symbolic register sizes?

After #9901 is merged, there are a few held functions which can't evaluate through Maxima or `n()`, I think. Since this behavior didn't exist at all before, this is ok, but should be rectified. Th…
