Why relational algebra is a procedural query language?
The syntax of a query in relational algebra essentially describes the query evaluation algorithm i.e. SELECT WHERE FROM --------------- I don't agree with the above answer. Notice that 'SELECT WHERE FROM' is fragmentary SQL. It does not describe an algorithm, or procedure, for obtaining the desired results. Rather, it describes the characteristics of the desired results and where they might be obtained. In fact, relational algebra is not inherently procedural. It involves closed collections of objects called relations and a set of permitted operations on these objects. Please see the link.
A combination of operations on variables and numbers is called an?
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.
