NOT.3:4.1 - Choose what the reading must produce

State the question, the expression and the information available outside it. Identify what would count as a useful result. Examples include the value of a formula, a permitted next action, whether two intervals overlap, or a consequence of a diagram’s relations.

Distinguish obtaining the expressed answer from establishing its use in the subject matter. Reading an interval from a schedule can answer what is planned; observing what happened needs the corresponding observation. The interpretation should identify which question it answers.

Specify the reader’s available operations. It may be reasonable to presuppose arithmetic, following a visible connection or a trained movement. Expose a less familiar operation if the intended reader could otherwise mistake its absence for a defect in the expression. A short prerequisite explanation can suffice; a capability that requires practice belongs in the appropriate learning method.
