Question

may it helps you.
The letters used to represent numbers are called literals or variables.
A quantity having a fixed numerical value is called a constant.
An expression which has a combination of constants and variables connected to each other by one
or more operation (+,-,X,+) is called an algebraic expression.
The parts of an algebraic expression separated by an addition or subtraction sign are called terms of
the expression.
Algebraic expressions having one term are called as monomials.
Algebraic expressions having two terms are called as binomials.
Algebraic expressions having three terms are called as trinomials.
Algebraic expressions having one or more than one term are called as polynomials.
The power or degree of a term is the sum of powers of all the variables in the term.
The term with the highest power decides the degree of the algebraic expression.
The terms having the same algebraic factors are called like terms.
The terms having different algebraic factors are called unlike terms.
Only like terms can be added or subtracted.
When we subtract like terms, we add the additive inverse of the term to be subtracted.
Algebraic expressions are used to write rules and formulas in a general form.​
