The passage around this formula
Collin, Ritort, Jarzynski, Smith, Tinoco and Bustamante tested the closely related Crooks fluctuation theorem directly on RNA hairpins pulled and relaxed with optical tweezers, comparing forward-unfolding and reverse-refolding work distributions and recovering folding free energies that matched independent estimates [ 2 ] . The forward and reverse work distributions cross at exactly the point where work equals F — a directly falsifiable prediction, and one their data confirmed. Toyabe, Sagawa, Ueda, Muneyuki and Sano later validated a generalized form of the same equality in a feedback-controlled Brownian particle, demonstrating that information gained through measurement and feedback…

Addition combines quantities; subtraction measures the signed difference between them. Parentheses show what is combined before the rest of the expression is evaluated.
