13000 / 125
= 13 X 8 X 125 / 125
= 104

9400 / 25 / 4
= 9400 / 100
= 94

125 X 64 X 25
= 125 X 8 X 8 X 25
= 1000 X 200
= 200 000

5800 / ( 50 X 29 )
= ( 50 X 2 X 2 X 29 ) / ( 50 X 29 )
= 4

183 + 17 X 50
= 33 + 150 + 17 X 50
= 33 + ( 3 + 17 ) X 50
= 33 + 20 X 50
= 1033

159.74 - ( 15.4 + 8.74 )
= 159.74 - 8.74 - 15.4
= 151 - 15.4
= 135.6

65.49 + 25.8 + 4.2
= 65.49 + ( 25.8 + 4.2 )
= 65.49 + 30
= 95.49

54 X 7.2 - 54 + 3.8 X 54
= 54 X ( 7.2 + 3.8 - 10 )
= 54 X ( 11 - 10 )
= 54 X 1
= 54

( 5.2 + 8.35 ) + ( 4.8 + 1.65 )
= ( 5.2 + 4.8 ) + ( 8.35 + 1.65 )
= 10 + 10
= 20

312.2 - 222.3 + 87.8 - 77.7
= ( 312.2 + 87.8 ) - ( 222.3 + 77.7 )
= 400 - 300
= 100

82.28 + 67.6 + 17.72 + 11.4
= ( 82.28 + 17,72 ) + ( 67.6 + 11.4 )
= 100 + 79
= 179

( 3692 / 52 - 71 ) / 385
= ( 923 / 13 - 71 ) / 385
= ( 71 - 71 ) / 385
= 0 / 385
= 0
