Answer 2

509 - (190-100:4) = 1) 100: 4 = 25 2) 190-25= 165 3) 509 - 165 = 344

Answer 3

854-(346-15·5)=854-(346-75)=851-271=580
287+(401-16·6)=287+(401-96)=287+305=592
502-(190-100:4)=502-(190-25)=502-165=337
420:6·5+639=70·5+639=350+639=989
600:3·4-327=200·4-327=800-327=473
560:7·3+586=80·3+586=240+586=826
