Abs(9 - n)
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.
A variable is a single letter that represents a number. For example x is a variable.An algebraic expression can contain variables, numbers, mathematical symbols, etcetera. An example of an algebraic expression is 3x+12.
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.
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.
It can be: 2x-25 or 25-2x or maybe the absolute value of (2x-25).
It depends what "x" is. ======== An algebraic expression representing the difference (subtraction) between 6 and some unknown number (represented by x).
