< p > Write methods to implement the multiply, subtract, and divide operations for integers. The results of all of these are integers. Use only the add operator.< / p >

Operations operations = new Operations();
operations.minus(1, 2); //returns -1
operations.multiply(3, 4); //returns 12
operations.divide(5, -2); //returns -2
