the order of operations
A mathematical phrase that contains operations, numbers, or variables is called an algebraic expression. Algebraic expressions consist of constants (numbers), variables (letters representing unknown quantities), and mathematical operations such as addition, subtraction, multiplication, division, and exponentiation. These expressions can be simplified, evaluated, or manipulated using algebraic rules and properties.
variables
The term for that is algebra.

A combination of numbers and operations is called a Numerical Expression.
That type of sentence is called a mathematical expression.
Because they can both have variables.
