Many subjects or fields of study have their own vocabulary: a list of words that are only used by that subject, or that people who study that thing use in a particular way. Maths works like this too: words such as "matrix", "field", "cross", "chance" or even "theory" have meanings different too their English meaning. Other words, like "calculus", "icosahedron" or "Jacobian" are used only by people who study maths. Any student of mathematics has to learn the language used as well as the concepts involved - they have to know the vocabulary.
A scale, in math as in other fields where measuring is required, is a set of numbers that measure something.
