Scalar
A scalar is a quantity that has only size (magnitude) and no direction, such as mass, length, temperature, or speed. Scalars are described by a single number with a unit.
They contrast with vectors, which also carry a direction, and they obey ordinary arithmetic.

Where it appears in Add Math
You meet Scalar in the Vectors chapter of SPM Additional Mathematics. Knowing the term precisely matters in the exam: questions often hinge on reading a keyword correctly, and because SPM marking is analytic, using the right definition in your working helps secure method marks.
Our teachers make sure a student can not only recite what Scalar means but use it fluently in a full solution.
The term in three languages
Because the SPM Add Math paper is bilingual (BM/EN), it helps to know this term in each language: Scalar (EN) · Skalar (BM) · 标量 (中文)
