First, let's convert the angles from degrees to radians:

sin(56°) = sin(56 π / 180) ≈ sin(0.977) ≈ 0.829
cos(26°) = cos(26 π / 180) ≈ cos(0.454) ≈ 0.894
cos(56°) = cos(56 π / 180) ≈ cos(0.977) ≈ 0.594
sin(26°) = sin(26 π / 180) ≈ sin(0.454) ≈ 0.436

Now, we can plug these values back into the expression:

0.829 0.894 - 0.594 0.436
≈ 0.739 - 0.258 ≈ 0.481

Therefore, sin(56)cos(26) - cos(56)sin(26) ≈ 0.481.
