Understanding Slang, Register, and Synonymy in Language
Synonym and Register
Synonymy
A relationship of ‘sameness of meaning’ that may hold between two words.
Register
A style or way of speaking adopted by a group. The factors defining a register are:
- Degree of formality (“formal”/“polite” vs. “informal”/“intimate”)
- Profession or trade (linguists, academics, mountain climbers, miners)
- Channel (postcard, CB radio talk, e-mail, internet forums)
- Plus anything else which may create a community feeling among people.
Cross-Varietal Synonymy

1.1 Location of Given Points in the Cartesian Plane
A plane, xy, formed by two perpendicular lines, is divided into four quadrants (I, II, III, IV).
The intersection point of these lines is called the origin (O), with coordinates (0, 0).
From the origin, you can observe positive and negative directions. Any point P in the plane is represented by ordered pairs (x, y). This system, used in analytic geometry, is known as the Cartesian plane.
To locate a point, distinguish the values of x and y. A positive

Problem Solving as Context (PSC)
For students to understand and make meaning out of the mathematics they learn in school, it should connect to the real world. Problem solving (PS) is the pedagogy that justifies teaching mathematics for real-life experience. To motivate students to realize the value of mathematics, the content connects to the real world, allowing them to gain PS experiences. PS motivates students, aiding their interest in specific areas and mathematical topics or algorithms by making
