It's profoundly unfair to lump mathematics in with economics. Economics has massive, massive problems that are only really being mildly addressed today: namely that its numerical differences with psych/sociology come from an Intro to Physics textbook rather than being derived independently. The mathematics is correct. 10 divided by 5 really is 2. The problem looks something more like 10 kg divided by 5 lb isn't 2 kg. It's 2 kg/lb. It's not the mathematics' fault that you got your translation into reality wrong.
