43=57

You love calculating?

Did you ever try to solve equations when looking at the plate of the car driving in front of you? Just to keep your brain busy?

Well, I did so for years, and I thought there might be other people in the world exercising their brain in the same way.

You now no longer need to take the road to get new numbers for which you want to try to find a solution.

The app comes with equations of four, five and six digits and you can compare your performance to that of other players.

The app is totally free, no ads displayed, no payable upgrade.
Just for fun and entertainment!

If you like it, show us some love by posting a nice review on Google Play.

Examples:
App proposes: 4357, you solve it with 4 * 3 = 5 + 7
App proposes: 5331, you solve it with 5 - 3 = 3 - 1

Six digits are easy to solve, five digits start to be a bit more complex, but 4 digits can be a real challenge, with sometimes no solution at all.

You can use the operands + - / * ** and √().

Parenthesis can be placed.

Two playing modes:
- Try to solve 25 Equations as fast as possible.
- Solve as many Equations as you can. Bonus points are awarded when your solution requires less operands than solution found by the app.

Select an operand and tap on the place where you want it to be added.
Move the = sign when needed.
