A polynomial is a type of algebraic expression. They differ in the number of terms that contain variables. An algebraic expression has at least 1 variable, while a polynomial has multiple terms with variables in it.

An equation has an equal = sign whereas an expression does not.

Evaluation is the process of finding the numerical value of an expression. For instance, suppose you wanted to know what x^3 was when x = 2. You would plug in 2 for x and get 2^3. This process is evaluation.Simplifying an expression on the other hand doesn't necessarily involve finding any particular value. For instance, suppose you started with the expression (x^3)/(x^2) then recognized that the numerator and denominator share a common factor of x^2 and so rewrote the expression as x. This is simplification because you've put the expression into an equivalent form that may be easier or more useful to deal with, but you have not found a specific value.You can also simplify numerical values -- for instance, 12/20 can be rewritten as 3/5. Often it's necessary to simplify a numerical expression after evaluating an algebraic one.

it has to have an x number in it.

Numerical expressions solely include numbers, while algebraic expressions may contain a variable like x. An example of a numerical expression is 1+2 and an example of an algebraic expression is 2x+3y=0.

A numerical expression uses numbers and operations. It also has an equal sign. An algebraic expression uses variables and operations. Unlike a numerical expression it does not have an equal sign.

Numerical expression: 59-34*6 Algebraic expression: 5x-3x+2 A numerical expression is limited to only numbers and can always be simplified to one number. An algebraic expressuion uses terms, more specifically a variable like x, and a constant like 2.

A numerical expression is an equation that contains only numbers. An algebraic expression is an equation that contains one or more variables and can also have numbers.

Numerical equations have only numbers and symbols, while algebraic equations have variables also.

Numerical Expression: 1.) 20+2-8 ( Or any other number with two symbols on math ) Algebraic Expression: 2.) h x 2 ( Or any other number using only one symbol an a letter ) The difference between a numerical and algebraic expressions is that numerical expressions use only numbers, but algebraic expressions use letters as variables to represent numbers.

A variable is a part of a term which can change. A coefficient is a numerical constant, associated with a variable. For example, in the term 3x^2 , 3 is the coefficient, while x is a variable.

Basically categorical variable yield data in the categories e.g sex (male, female), modes of transport (Bus, railway, etc) and numerical variables yield data in numerical form e.g. age (0-100), number of accident on a certain highway (0,1,2,..).
