A numerical expression is a mathematical phrase involving only numbers and one or more operational symbols. The following are some examples of numerical expressions. For example, the numerical expression 4 + 20 - 7 in the example above simplifies to the number 17.
A monomial is an expression that is either:1) a numeral,2) a variable,or 3) the product of a numeral and one or more variables.A variable can be thought of as the product of the numeral 1 and the variable, thus making it a monomial.
The numeral 8 is an example of the Hindu-Arabic counting numerals. That is to say the numbers that we use today which replaced Roman numerals.
A bar over a Roman numeral multiplies the base numeral by 1000. Example: V with a bar over it = 5000
for example a is numeral 1, b is numeral 2, c is 3, d is 4, e is 5 f is 6 and so on
You can write the expression for 279 minus 125 in numeral form as ( 279 - 125 ). In algebraic terms, you can represent it as ( x - y ), where ( x = 279 ) and ( y = 125 ). Both forms convey the same mathematical operation of subtraction.
A combination of numbers and operations is called a Numerical Expression.
a formula
A non-numeral is any word or symbol that represents a numeral, but is not a numeral. Therefore, an example of a non-numeral less than ten is three.
A monomial is an expression that is either:1) a numeral,2) a variable,or 3) the product of a numeral and one or more variables.A variable can be thought of as the product of the numeral 1 and the variable, thus making it a monomial.

"Why is a constant a monomial?"The short answer is because a constant is a special typeof monomial.The reason for this is that the definition of a monomial reads: A monomial is"An expression that is eithera numeral (= a numerical expression which names a particular number, IE a constant),a variable,or a product of a numeral and one or more variables.""constant (monomial): A monomial consisting of a numeral only; a term with no variable factor. "
Expression
A algebraic expression is when you have a pro numeral equal to different variables when substituted with their values give the pro numeral. e.g. Area of a circle = πr2 A = πr2 [Where r = the radias of the circle (distance from the centre point of a circle to any point of the perimeter.)]
