Вычисления
$80 \overset{2}{:} (8 \overset{1}{*} 10) \overset{3}{*} 473 = 473$
1) 8 * 10 = 80
2) 80 : 80 = 1
3) 1 * 473 = 473
 
$300 \overset{3}{-} (60 \overset{2}{-} 60 \overset{1}{:} 3) = 260$
1) 60 : 3 = 20
2) 60 − 20 = 40
3) 300 − 40 = 260
 
$700 \overset{2}{+} 42 \overset{3}{+} 8 \overset{1}{*} 4 = 774$
1) 8 * 4 = 32
2) 700 + 42 = 742
3) 742 + 32 = 774
 
$0 \overset{1}{*} 9 \overset{2}{+} 16 = 16$
1) 0 * 9 = 0
2) 0 + 16 = 16
 
$0 \overset{2}{*} (9 \overset{1}{+} 16) = 0$
1) 9 + 16 = 25
2) 0 * 25 = 0
 
$9 \overset{2}{+} 16 \overset{1}{*} 0 = 9$
1) 16 * 0 = 0
2) 9 + 0 = 9
