Составь программу действий и вычисли:
14 : 7 * 9 + 6 * (13 − 7);
15 + 7 * (18 : 3) − (9 + 8);
4 * 7 − (5 * 6 − 3) + 8 * 3;
(20 : 5 + 7) − 3 * 3 + 27 : 9.
$14 \overset{2}{:} 7 \overset{3}{*} 9 \overset{5}{+} 6 \overset{4}{*} (13 \overset{1}{-} 7) = 2 * 9 + 6 * 6 = 18 + 36 = 54$;
$15 \overset{4}{+} 7 \overset{3}{*} (18 \overset{1}{:} 3) \overset{5}{-} (9 \overset{2}{+} 8) = 15 + 7 * 6 - 17 = 15 + 42 - 17 = 57 - 17 = 40$;
$4 \overset{3}{*} 7 \overset{5}{-} (5 \overset{1}{*} 6 \overset{2}{-} 3) \overset{6}{+} 8 \overset{4}{*} 3 = 28 - (30 - 3) + 24 = 28 - 27 + 24 = 1 + 24 = 25$;
$(20 \overset{1}{:} 5 \overset{2}{+} 7) \overset{5}{-} 3 \overset{3}{*} 3 \overset{6}{+} 27 \overset{4}{:} 9 = (4 + 7) - 9 + 3 = 11 - 9 + 3 = 2 + 3 = 5$.
