between algebraic language with figurative, natural and arithmetic language.
Using the 3uv Model (3 uses of the variable) to describe the comprehension of
the different aspects that characterize the variable as the acting of the students
when they face tasks.
Key words: mathematical education, difficulties, high school teaching, algebraic
thinking, variables.
