so, I have to type in the problem (3e+2i)(−3+πi)...I enter in (3*e+2*I)*(-3+pi*I) on SageMath but come up with the answer, -30.74772176 + 19.61920267*I....am I dumb or is the correct answer?
Works For Me (TM):
sage: (3*e+2*I)*(-3+pi*I)
(I*pi - 3)*(3*e + 2*I)
sage: ((3*e+2*I)*(-3+pi*I)).n()
-30.7477217633110 + 19.6192026680207*IWhat are you using (Sage version, interface, etc..) ?
just SageMath?
As you might notice, it is not the command that was entered.
so is -30.7477217633110 + 19.6192026680207I , the correct answer? Because I don't think there is another way to type (3e+2I)(-3+pi*I)
What do you mean by "the correct answer" ? Is it homework ? What are you trying to understand ?
I think ariaaaaaaaa is a troll !
If you enter
sage: (3*e+2*I)*(-3+pi*I)Sage will return:
(I*pi - 3)*(3*e + 2*I)What did you type to get the answer -30.74772176 + 19.61920267*I ?
I entered (3e+2I)(-3+piI) and somehow got that answer
This is not possible.

Is it homework ?
Is it possible you redefined
eandpi? Because if you did something likee = 2.718281828; pi = 3.141592654before computing the result, because then yes you'll get a numerical answer (and it would be a silly thing to do becauseeandpiare already built into Sage and can be given to high precision (e.g.pi.n(digits=100) => 3.141592653589793238462643383279502884197169399375105820974944592307816406286208998628034825342117068)`
