Re: heisenberg's

If what you mean is that you can divide or multiply on either side by the same thing then yes

Yes, but generally the question will ask you to find the minimum value so you can just use the equal sign in that case.

If the question asks to find the minimum value for uncertainty in position or uncertainty in momentum, then the , >= sign acts as an equal sign because the delta x or delta p will be greater than or equal to the answer, indicating a minimum value for the indeterminacy.

Re: heisenberg's

Yes, we use = to get the minimum number.

Re: heisenberg's

The >= sign just means that the uncertainty can be infinitely greater (which makes sense). Usually, I think you would just use it as an equal sign because it is the minimum uncertainty
