This application is a mental arithmetic game which lets you do some maths with fun.
Rules of the game
Six numbers are randomly chosen among 24 numbers distributed as follows:
All numbers from 1 to 10 appear twice.
Number 25 appears once.
Number 50 appears once.
Number 75 appears once.
Number 100 appears once.
Another number is chosen between 100 and 999.
You must find this number by combining the others with arithmetic operations : addition, substraction, multiplication and division. Divisions are not allowed when the result in not an integer and substractions must have a positive result.
Each number from the six must be used only once but it is not mandatory to use all of them. This application solves any submitted problem and lets you train with randomly chosen problems.
Example
Number to find: 699
Available numbers: 3, 5, 7, 8, 10, 100
Solution:
100 x 7 = 700
700 - 8 = 692
692 + 10 = 702
702 - 3 = 699
