Question

Выполните действия: а) 703-21×(361-349), б) 2346 : (209-186) ×15, в) 6422-24× (372:12), г) 2678 : (506-480)+297

Answer 1

а)
$703 - 21 times (361 - 349) = \ = 703 - 21 times 12 = \ = 703 -252 = \ = 451$
б)
$2346 div (209 - 186) times 15 = \ = 2346 div 23 times 15 = \ = 102 times 15 = \ = 1530$
в)
$6422 - 24 times (372 div 12) = \ = 6422 - 24 times 31 = \ = 6422 - 744 = \ = 5678$
г)
$2678 div (506 - 480) + 297 = \ = 2678 div 26 + 297 = \ = 103 + 297 = \ = 400$
