At the lower levels, simple basic knowledge of the 4 basic arithmetic operations is sufficient to solve the tasks. At the higher levels you need a real professional to solve the tasks in your head. For example, for multiplication and division, level 3 corresponds to the small multiplication table, level 4 corresponds to the large multiplication table. Each level has 6 to 16 tasks and corresponding solutions. There are two ways to connect solutions to tasks. Either you find the solution to the task marked in red, then simply tapping on the correct solution is enough. Or you find the solution to any task, then you can drag the solution box onto the task and connect it to it. If you really don't know any further, the help function will provide you with the right solution. Now have fun exploring your abilities.
