Explain in Detail :Definition of Expression:
An expression is a unit of code that returns a value.
An expression can be a simple value, such as a number or a string, or it can be a more complex value that is built up from simpler values.
In Python, an expression can be written in parentheses, like this: (1 + 2)
This expression calculates the sum of 1 and 2 and returns the value 3.
How to Simplify Algebraic Expressions?
To simplify algebraic expressions, one can use the order of operations. This is the order which can be abbreviated PEMDAS:
P: Parentheses first
E: Exponents (ie Powers and Square Roots, etc.)
MD: Multiplication and Division (left-to-right)
AS: Addition and Subtraction (left-to-right)
What is an Algebraic Expression?
An algebraic expression is a mathematical statement involving one or more variables and constants that is formed by using the operations of addition, subtraction, multiplication, and division.
The Terminology Used In Algebraic Expressions:
term: a number, letter, or symbol that stands alone in an algebraic expression and is multiplied by a coefficient
coefficient: a number that is placed in front of a term and that multiplies the term
variable: a letter that stands for a number that may change in an algebraic expression
Types of Algebraic expression:
1. Polynomial: a polynomial is an algebraic expression that consists of a sum of one or more terms, each of which is a monomial. A monomial is an algebraic expression that consists of a single term.
2. Trinomial: a trinomial is a polynomial that consists of three terms.
3. Binomial: a binomial is a polynomial that consists of two terms.
4. Monomial: a monomial is an algebraic expression that consists of a single term.
