In this math problem we will check if you understand Cartesian coordinate system and function graphs. To get the right answer you need to know how function relates to the X- and Y-axis and how to determine the coordinates of important points..

This challenge is a combination of different mathematical rules and operations. First of all you need to know what "X" means and how it is used instead numbers. Secondly, you should know fractional numbers perfectly well. Thirdly, you need to be skilled at factoring.

In this challenge we will check if you can work with different kinds of roots (square root, cube roots) and use them in different equations. To solve the task given you need to identify with what roots you are dealing with, extract them and get the right answer by calculating their sum.

To solve this challenge you need to understand the difference between less-than and greater-than signs as well as what they mean when used together with variable “x”. You need t simplify and transform the inequality until it matches one of the answers given.

In this challenge we will test if you understand to simplify and expression. You are given a complex equation full of different variable, natural numbers, parentheses and mathematical operation. To get the right answer you need to apply every mathematical operation in the correct order.

To solve this challenge you need to understand that how to combine a word problem and a mathematics equation. Your task is to replace one of the variables in the formula and solve this equation as equation with one unknown.

In this task student’s understanding of fractional, rational and irrational numbers will be tested. To solve the challenge given you need to know what multiplicative inverses are and how they can be calculated. You should also know how multiplicative inverses can be expressed and what they are used for.

In this challenge we will test if you know what reciprocals are. To solve this problem you need to know characteristics of different kinds of numbers such as natural, rational, irrational, negative and others as well as understand what is “0”, its peculiarities and what this number means when used in different math operations.

This math challenge will test your understanding of math powers and how they interact in different math operations. You are given a variable in different powers; your task is to multiply them.

In this challenge you are given a graphical representation of a certain linear function. To get the right answer, inspect the slope of the line and find the coordinates where the line intersects the X and Y axis.
