Question

With this new idea of variables, Tina was gazing at the stars when the North Star caught her attention. When she asked Ramses about that bright shiny piece in the sky, she found out that position of that star is fixed. Which part of algebraic expressions exhibits similar characteristics as a North Star?

Answer 1

The position of the North Star, also known as Polaris, is known to be fixed in our sky. This is analogous to a “constant” as the value of the constant remains same. A constant is a number on its own which is a fixed value.
