**Video tutorial**

### I´m studying at secondary school, math is quite fun for me, but it is too much. I don´t want to keep on calculating problems from textbooks or from worksheets. I am looking for something interesting even if it is repeating the things we took up last year.

### Our teacher has created written tests from this website. I want to look at the problems which could be on the tests.

### I will try it, I need to practice functions with absolute values.

Click on the area Function. You will find there Linear functions, Quadratic functions, Rational functions, Functions with absolute values, Power and radical functions, etc. Choose Functions with absolute values, select the number of questions and the level.

### What is the level?

Level A contains the curriculum, which schools usually begin with. In functions with absolute values there are problems for practicing linear functions with one absolute value. Level B contains a curriculum linked to functions with multiple absolute values and their properties. Level C contains a more complicated curriculum or a curriculum which is not dealt with at all schools, and thus for problem functions with absolute values in absolute values.
