Chapter 12 – Algebraic Expressions
A constant is a term having a fixed numeral value. A variable is not a fixed value and can be assigned or replaced with a constant as per requirement. Algebraic equations are formed from variables and constants. This chapter will teach the students about constant, terms of expression, coefficient of a term, algebra as patterns, writing number patterns & rules related to them, writing patterns in Geometry, the definition of variables, formation of algebraic expressions, like & unlike terms, monomial, binomial, trinomial, & polynomial terms, addition & subtraction of algebraic equations, use of algebraic equation in the formula of the perimeter of figures, and use of algebraic equation in the formula of area of figures.
