In some texts, one writes $\mu(B\setminus A) = \mu(B) - \mu(A)$ whenever $\mu(A) < \infty$ (or $\mu(A)$ finite), and the formula holds in $[0,\infty]$ with $\infty - c = \infty$ for finite $c$.

Solutions to specific foundational problems in Cohn's text are frequently cited in academic contexts: In some texts, one writes $\mu(B\setminus A) =
