How to play
The glass is filled with balls that have numbers on them. Your task is to find balls that have an integer common devisor. The more integer common devisors, the higher score you will get. (An integer common devisor is a number that devides chosen numbers without a remainder).
Match 3 balls: You have to find three balls with an integer common devisor. The time is without limit.
Timed game: You have to find several balls within a timeframe. The more balls you find, the better! Time limit gets stricter with each subsequent attempt.
Dividers is an amusing math game similar to a bubble shooter. The game suits well both adults and children.
Divisibility of numbers 2
2 share all even natural numbers , for example: 4,8,12
Divisibility properties 3
3 divided all the natural numbers , the sum of digits is a multiple of 3 . Example:
27 ( 7 + 2 = 9 , 9/3 = 3);
Divisibility by 4 numbers
Divided into 4 all the natural numbers , the last two digits of which are 0 or a multiple of 4 .
164 (64/4 = 16) ;
Divisibility properties 5
5 share all natural numbers ending in 5 or 0 .
For example: 25.
Divisibility properties 6
6 share those natural numbers that are divisible by 2 and 3 simultaneously (all even numbers are divisible by 3).
For example: 36 ( B - even 3 +6 = 9 , 9/ 3 = 3).
Criterion for divisibility by 7
The number is divided by 7, and when the result of subtracting twice the last digit of this number is divisible without the last 7 digits (e.g. , 259 divided by 7 , so as the 25 - ( 2 x 9) = 7 divided by 7 ) .
Divisibility properties 9
On 9 share those positive integers , the sum of digits is a multiple of 9.
279 ( 2 + 7 + 9 = 18 18/9 = 2).
Divisibility properties 10
10 divided all natural numbers ending in 0 .
For example : 100;
Divisibility properties 11
Divided by 11 , only those natural numbers whose sum of digits , even occupying space is the sum of digits occupying odd places , or the difference between the sum of digits of odd places and the sum of digits even multiple of 11 seats .
2365 (2 and 8 +6 = 3 +5 = 8);
