Пошаговое объяснение:
| a | = a
| - a | = a
1) |-73,3| + |9,24| - |23| = 73,3 + 9,24 - 23 = 59,54
2) |-66,4| - |-8,6| + |-23,2| = 66,4 -8,6 +23,2 =81
3) |3,375| + |-5,625| - |-9| = 3,375 + 5,625 -9= 9-9=0
4) |35,2| - |-2 5/6| + |-29 19/30|= 35,2 - 2 5/6 + 29 19/30 = 35 2/10 - 2 25/30 + 29 19/30= 35 1/5 - 27 14/30 = 35 1/5 - 27 7/15 = 35 3/15 - 27 7/15 = 7 11/15
