Among other subject areas, as a teacher of numeracy, the pure science of maths informs that there is a proven peer evaluated equation for the correct number of muzzleloaders:
At any given time on a periodic timeline, add up the number of muzzleloaders that you currently have, then add one.
Remarkably, this equation holds true for any given point along the timeline.
This same equation holds true for motorcycles, knives, books and other desirable artefacts. A peer did try to evaluate the equation in relation to girlfriends but found out further multiple subtraction was required to gain equilibrium.
