Re: I need to review modulus function

My review for the question from 800score.com is as follows: For understanding the above problem the modulus function should be clear. You can refer in detail regarding the modulus here http://800score.com/guidec6view1b.htmlfunction
109x3 = 12
The modulus function can take both positive and negative values. When the modulus function is positive ie x3 (>=) 0
109(x3) = 12 9(x3) = 2 (x3) = 2/9 x = 2/9+3 = 25/9
But, this value doesn't satisfy x3 (>=) 0 So,there is no solution When the modulus function is negative ie x3 (<=) 0
10+9(x3) = 12 9(x3) = 2 x3 = 2/9 x = 29/9
But, this value doesn't satisfy x3 (<=) 0 So,there is no solution
Hope it helps.
Best of luck!!
