Description

rite methods to implement the multiply, subtract, and divide operations for integers. The results of all of these are integers. Use only the add operator.

You should implement following methods:

• Operations()  constructor
• minus(a, b)  Subtraction, returns a - b
• multiply(a, b)  Multiplication, returns a * b
• divide(a, b)  Division, returns a / b

Example:

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

Note:

• You can assume inputs are always valid, that is, e.g., denominator will not be 0 in division.
• The number of calls will not exceed 1000.
