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.
Expression has no answer. a equation has an answer
an algebraic expression has no = sign. it could be like x+4, but an equation has to have an = sign. like x+4=5
Equation: x+3=3+x (notice the equal sign: equal; equation)Expression: x+3 (notice no equal sign)
The difference is that an algebraic expression has numbers, symbols and variables, but a verbal expression has only words.
An algebraic expression doesn't have an equal sign (e.g. 4x+7) whereas an algebraic equation does (e.g. 4x+7=19). 4x=19-7 4x=12 x=12/4 x=3
i think what makes an equation an equation is y= whatever
An expression simply contains no equals sign. This is an expression: 2x + 4y + 3 An equation contains an equals sign. This is an equation: 2x + 4y + 3 = 0
An expression has no equal sign whereas an equation does have an equal sign
They both are made up of algebraic terms but an expression does not contain an equality sign whereas an equation does have an equality sign.
An equation is a ploblem with no answer and an expression is a problem with an answer so you'll get different answers with an equation and an expression.
An algebraic expression contains one or more variable.Example : 12n
algebric uses variables and numerical uses numbers
an equation has an equals sign.
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.
The differnce between a verbal model and a algebraic model is that a verbal model is an equation written in words and a algebraic model is solving the equation from the verbal model.
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.
A polynomial is always going to be an algebraic expression, but an algebraic expression doesn't always have to be a polynomial. An algebraic expression is an expression with a variable in it, and a polynomial is an expression with multiple terms with variables in it.
The difference between these two is that an expression only contains variables, numbers, and mathematical symbols, and an equation contains two expression with an equal sign that separate them. For example, while an expression is "2x-1", an equation is "2x-1 = 5x."
Simply put, an expression does not need an equal sign, while an equation does. Equation: x+y=z Expression: x+y
Numerical equations have only numbers and symbols, while algebraic equations have variables also.
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.
