Can a mathematical expression have no variables?
Yes, a mathematical expression can have no variables, but such an expression is usually not very useful. An example of a valid expression without variables is: 1+1=2
Does a mathematical expression have to have variables?
Yes. Expressions cannot be expressed without variables. There are numerical expressions for ex. 2 + 3 is an expression without variables.
What is an expression which combines variables numbers and at least one expression?
It is a bigger expression.
What is an expression that is written using one or more variables?
An expression written with 1 or more variables is called an equasion
What expression contains variables?
equations

What is a type of expression that contains a variable or variables?
An algebraic expression is a type of expression that contains a variable or variables.
What is a collection of numbers variables operations and grouping symbols called?
They are terms of an expression or an equation

What is a expression with variables called?
It's called an algebraic expression.
Is it possible to write an algebraic expression with two variables and no operations?
Yes, an algebraic expression needs no operation and can have multiple variables.
The of an expression is the result when the variables in an algebraic expression are replaced by numbers and the expression is simplified?
Value
An algebraic expression is a combination of letters called what?
variables
What does the value of an expression mean?
If you replace variables in an expression by numbers (in case there are any variables) and then do the indicated operations, you get a number. That final number is the "value" of the expression.
What expression contains variables?
equations
