You replace each variable by its value. Then you do the indicated calculations.
variable expression(;
An algebraic expression can have a mixture of numbers and variables, but it does not contain an equals sign.
Numerical Expression
It is simply a more complicated expression.
Yes. A variable expression is also known as an algebraic expression. An equation consists of variable expressions on each side of an equality.
variable expression, I believe.

No, because numbers never vary. A variable expression must have something in it that can take on different values, usually a letter, like 'x' for example.

algebraic expression consists of numbers and operations
A variable expression includes variables.
An algebraic expression can have a mixture of numbers and variables, but it does not contain an equals sign.
This is called algebra. In algebra you can have many operations. You can add, subtract, multiply, divide, square, cube, square root, factor, or distribute. There are others but these are the main ones. You use these operations to find the numerical value of the variable.
In the context of algebra, "4d" would typically be considered a numerical expression rather than a variable. A variable is typically a letter or symbol that represents an unknown quantity that can vary, while a numerical expression is a combination of numbers and mathematical operations. In this case, "4d" represents the product of the number 4 and the variable "d," making it a numerical expression.
It is the domain of the expression.
It is an expression.
