Human: Lindsay has 4 dolls with blonde hair; four times more dolls with brown than blonde hair; 2 fewer dolls with black than brown hair. How many more dolls with black and brown hair combined does Lindsay have than blonde-haired dolls? Assistant: 
How many brown-haired dolls does Lindsay have? ** Lindsay has 4 x 4 = <<4*4=16>>16 brown-haired dolls.
How many black-haired dolls does Lindsay have? ** She has 16 - 2 = <<16-2=14>>14 black-haired dolls.
How many black and brown hair dolls does Lindsay have? ** Thus, Lindsay has 16 + 14 = <<16+14=30>>30 black and brown hair dolls combined.
How many more dolls with black and brown hair combined does Lindsay have than blonde-haired dolls? ** Therefore, she has 30 - 4 = <<30-4=26>>26 more dolls with black and brown hair combined than blonde-haired dolls.
