My son just gave my cat an algebra test. You know, “very special math with letters AND numbers in it”. This also involves the speeds known as “constract” and “sunstrakt”, which are 900 mph faster than the speed of light, and 910 million miles per hour faster than the speed of light, respectively. Although, since the symbols for constract and and the speed of light are both “c”, I think this might be a bit confusing. But, apparently Peanut (the cat), can handle such ambiguities, and has been performing rather well on these tests.
