(6-4,94)*2,5-2,35= 28,6+11,4*(6,595+3,405)= 20,4*6,5+3,8*18= 7,2*3,6-4,8*5,4= 0,18*(8,2+3,75)-1,051= 67,45-7,45*(3,8+4,2)

Let's break down each calculation step by step:

(6-4.94)2,5-2,35 = 1.06 2.5 - 2.35 = 2.65 - 2.35 = 0.30

6+11.4(6.595+3.405) = 6 + 11.4 10 = 6 + 114 = 120

20.4 6.5 + 3.8 18 = 132.6 + 68.4 = 201

7.2 3.6 - 4.8 5.4 = 25.92 - 25.92 = 0

0.18*(8.2+3.75) - 1.051 = 2.775 - 1.051 = 1.724

67.45 - 7.45(3.8+4.2) = 67.45 - 7.45 8 = 67.45 - 59.6 = 7.85

So, the final results are:
