2. TL: 

   2575 + 37 – 2576 – 29

   = ( 2575 – 2576) + (37 -29)

   = -1 + 8 = 7

   34 + 35 + 36 + 37 – 14 – 15 – 16 – 17

   = ( 34 – 14 ) + ( 35 – 15 ) + ( 36 – 16 ) + ( 37 – 17 )

   = 20 + 20 + 20 + 20 = 20.4 = 80

   4573 + 46 – 4573 + 35 – 16 – 5

   = ( 4573 – 4573 ) + ( 46 -16 ) + ( 35 – 5 )

   = 0 + 30 + 30 = 60

   32 + 34 + 36 + 38 – 10 – 12 – 14 – 16 – 18

   = ( 32 – 12 ) + ( 34 – 14 ) + ( 36 – 16 ) + ( 38 – 18 ) – 10

   = 20 + 20 + 20 + 20 – 10

   = 20.4 – 10

   = 80 – 10 = 70
