Calculators are not permitted for secondary-level entrants, but geometrical aids such as rulers, compasses, protractors and paper for working are permitted.
This term may be used to include not only stationery, but such items as pocket calculators, display boards, compasses and protractors, lunchboxes, and the like.
Many modern compasses incorporate a baseplate and protractor tool, and are referred to variously as orienteering, baseplate, map compass or protractor designs.
