Question 457165
At least 2 items are required to have a difference.
There cannot be a difference between the solution of anything.
-----------
PS  For there to be a "same difference", which is commonly said, there have to be 2 differences, which requires a minimum of 3 items.
"same difference" usually is mistakenly said when there's no difference, and it's actually "same thing."
Making sense seems to be a lost cause.
Don't even mention "hopefully."
