hey i was just thinking how matrices aren't supposed to be commutative? well i was just thinking, what if the matricees were equal? and i was like ha! im so cool! take that mr logic. so yea, so far i have a couple rebelious matricees a*b where a=1 by 1 and b= 1 by 1 a*b where na=b a*b where a^n=b a*b where a= identity a*b where na=b and a = identity a*b where a = null a*b where a= mutliple of identity and b= multiple of mirrored identity so, my questiono is this, can you help me be a good little poindexter and come up with a couple others?
