|25 - 24 -10| - (28 - 30 + 4)
= |1 - 10| - (-2 + 4)
= |-9| - 2
= 9 - 2
= 7
-(-73) + (44 - 94 + 27) + 94
= 73 + (-50 + 27) + 94
= 73 + (-23) + 94
= 73 - 23 + 94
= 50 + 94
= 144
(-33 + 108 - 75) - (108 + 25)
= (75 - 75) - 133
= 0 - 133
= -133
120 - (-2 + 120 - 18) - 92
= 120 - (118 - 18) - 92
= 120 - 100 - 92
= 20 - 92
= -72

673+458 -73-58
= (673 - 73) + (458 - 58)
= 600 + 400

234+108+266+177+92+183
= (234 + 266) + (108 + 92) + (177 + 183)
= 500 + 200 + 360
= 700 + 360
= 1060

73 . 35 + 27 . 19 - 20 . 73 + 81 . 27 + 85 . 73
= 73 . ( 35 - 20 + 85 ) + 27. ( 19 + 81 )
= 73 . 100 + 27. 100
= ( 73 + 27 ) . 100
= 100 . 100
= 10 000
