Edit: /usr/share/zsh/5.5.1/help/let (323B)

let arg ... Evaluate each arg as an arithmetic expression. See the section `Arithmetic Evaluation' in zshmisc(1) for a description of arithmetic expressions. The exit status is 0 if the value of the last expression is nonzero, 1 if it is zero, and 2 if an error occurred.
