yes.

When the value of a variable in an algebraic expression changes, the value of the expression can change.

Algebraic expressions may contain variables but they are not normally called variables. In fact, if they are related to identities, they need not be variable. For example, (4x2 + 8xy + 4y2)/(x + y)2 is an algebraic expression, but it is not a variable: it equals 4.

They are identical or equivalent.

It is an expression of algebraic terms with no equality sign

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.

Yes. A variable expression is also known as an algebraic expression. An equation consists of variable expressions on each side of an equality.
