MindCalc Arithmetic Trainer

Train your mental arithmetic ability with MindCalc!

This is NOT your standard "what is 7 * 13?" type of game but here the result is already known and an arithmetic operator is given. Now you need to pick two numbers out of 9 to make this equation happen.

The faster you solve your equation, the more points you gain.

But if you make a mistake you need to start all over - so be careful!

For an extra kick choose the highest difficulty where your score will be reset to zero in case you run out of time.

You can also compete against another person to see who has stronger mental arithmetic skills!
