Let's break down the calculation step by step:

Calculate the values inside the parentheses first:
23,83 + 54,58 = 78,41
1,202 + 0,698 = 1,90
3,53 - 1,89 = 1,64

Perform the multiplication operations:
78,41 • 1,90 = 149,038
2,1 • 1,64 = 3,444

Perform the subtraction operation:
149,038 - 3,444 = 145,594

Therefore, the final result of the calculation is 145,594.
