2. int a = 5, b = 2;
   
3. System.Console.WriteLine("a + b = " + (a + b));
   
4. System.Console.WriteLine("a - b = " + (a - b));
   
5. System.Console.WriteLine("a * b = " + (a * b));
   
6. System.Console.WriteLine("a / b = " + (a / b));
   
7. System.Console.WriteLine("a % b = " + (a % b));
   
8. System.Console.WriteLine(5 / 2);
   
9. System.Console.WriteLine(5 / 2.0);
   
10. System.Console.WriteLine(5.0 / 2);
    
11. System.Console.WriteLine(5+2*3);
    
12. //常用數學方法
    
13. System.Console.WriteLine("--------------------\n"+System.Math.Abs(-10));//絕對值
    
14. System.Console.WriteLine(System.Math.Pow(2,3));//次方
    
15. System.Console.WriteLine(System.Math.Sqrt(64));//根號
    
16. System.Console.WriteLine(System.Math.Max(2, 100));//最大值
    
17. System.Console.WriteLine(System.Math.Min(2, 100));//最小值
    
18. System.Console.WriteLine(System.Math.Round(3.5));//四捨五入
