Mathametics is the science of precise observation where the space and surroundings are well defined. By changing the configuration, one can get different results, but that is not maths. For example, if one takes a rectangular post card and cuts off one corner by a sharp scissor, one would find there are five corners formed on the card. This does not mean 'Four minus one produces Five'. Similarly, the three angles of a triangle drawn on a plane paper add up to 180'. But if the triangle is drawn on the surface of a foot-ball, the sum will be more than 180'. The poser 2 X 2 = 5 is a similar proposition.

I can tell you with an almost 100 percent certainty that the professor that did this, or anyone that did it did a very interesting thing such as dividing by 0, as you cannot multiply 2 and 2 to get 5, because 2*2 does not =5 it is proven, to disprove it would require re-writing the rules of math.

There is a common proof of such things that is used to fool first year algebra students. It involves disguising 0 so you can divide by it with the naive realizing what you are doing. If you search the answers here on 1 = 2 or some other such false statement, I'm sure you can find more than enough examples. It gets posted multiple times every day.

A similar observation can be made that, if a triangle is posed in a flat universe, the angled would add up to 180 deg. If it is posed in a closed universe, they will add up to less than 180 deg. Finally, if it is posed in an open universe, they will add up to more than 180 deg. This is known as a special field in math as "Virtual Background Mathematics and Geometry", math of figures in different backgrounds.
I think.

No. In the context of the natural numbers as defined by Peano's axioms with the equality relation defined in the usual way, this result is a contradiction.

I saw this done by a skilled math professor of mine years ago.. It's a very long and involved equation and took up every blackboard on every wall of the classroom, but it can be done.
