APLs use a negative sign distinguished from minus as a different character. Underscore followed by a number specifies a negative number. APLs also process the operations from right to left, evaluating parenthesized expressions when the interpreter comes to them. In J, unary plus returns complex conjugate, which won't affect the outcome of this experiment.
