>>12939034His argument isn't that dumb, since he is saying that "+" may refer to a different operation than addition as it is defined mathematically. e.g. in chemistry, you can have combustion reactions such as that of Propane () can be viewed as "1+5=3+4" since combination can be interpreted as a form of addition different from that which we use in arithmetic.
If you redefine addition such that 2+2=5 is true, then it is true. Of course, it's not particularly relevant mathematically, but that doesn't make his claims less true.
