This app deals with one of the most basic algebras in the world. You don’t need to have any algebraic knowledge. Questions in this app, i.e. block equations, can be solved by performing arithmetic operations such as addition, subtraction, multiplication, and division. The traditional methods of solving an equation or simultaneous equations are not necessarily the easiest ways to solve block equations.

The main rules of block equations:
- Unknowns of block equations are represented by blue or orange blanks.
- You have to find the missing values of the blanks from among five integers 0, 1, 2, 3, and 4.
- When one question has multiple blanks of the same color, they are to be filled with the same values.
- When two block equations are to be solved together in a question, the solutions must satisfy both equations simultaneously.
- One question may have more than one solution. You have to mark all the solutions before tapping the answer button.
