While mathematics is naturally the main focus, all other STEM fields are also in scope, namely biology, chemistry, computer science, earth sciences, economics, engineering and physics.
Concepts beyond K12 lie outside of the initial Core list. For example, when two vertical bars surround an argument to mean a group-theoretic “order”, that Open concept will not be included in Core, unless the overall Core scope is increased to K14.
For example, we would prefer “power” to “exponentiation”, although that creates a tension with the use of “power” in physics.
That choice is motivated by “power” being the more common name in present-day communication, as well as by mathematical uses of “power” being more widespread than the physics concept.
Similarly, we may prefer “gcd” to “greatest-common-divisor” due to brevity, while still adding an informal note clearly stating the connection between the two.
ここに列挙した条件は, 事象の種類に対してpropertyの名前を加える際にも適用されます.
The conditions enumerated here also extend to adding property names for kinds of objects.
For example, marking an <mtable> holding multiple equations with intent=":system-of-equations",
marking a unit expression, such as meters-per-second, with intent=":unit",
or marking the water molecule <mrow><msub><mi>H</mi><mn>2</mn></msub><mi>O</mi></mrow> with intent=":chemical-formula".
