Hint for students
Define the variable, translate relationships carefully, and check expressions or solutions with a numerical value.
Common mix-up
A variable is not always one hidden fixed number; it can vary across a domain. Algebra is usually uncountable in classroom English, while specialists may write about an algebra or several algebras as particular mathematical systems. Algebra and arithmetic are connected, not opposites.
