==Arithmetic Operators==

C# defines the following arithmetic operators:
Operator
Meaning
+
Addition
-
Subtraction (also unary minus)
*
Multiplication
/
Division
%
Modulus
++
Increment
--
Decrement
When / is applied to an integer, any remainder will be truncated.
For example, 10/3 will equal 3 in integer division.

<source lang="csharp">using System;
class MainClass
{
static void Main(string[] args)
{
int a,b,c,d,e,f;
a = 1;
b = a + 6;
Console.WriteLine(b);
c = b - 3;
Console.WriteLine(c);
d = c * 2;
Console.WriteLine(d);
e = d / 2;
Console.WriteLine(e);
f = e % 2;
Console.WriteLine(f);
}
}</source>

==Compound operator==

<source lang="csharp">using System;
public class CompoundAssApp
{
public static void Main(string[] args)
{
int nCalc = 10;
nCalc += 5;
Console.WriteLine(nCalc);

nCalc -= 3;
Console.WriteLine(nCalc);

nCalc *= 2;
Console.WriteLine(nCalc);

nCalc /= 4;
Console.WriteLine(nCalc);

nCalc %= 4;
Console.WriteLine(nCalc);
}
}</source>

==postfix and prefix==

<source lang="csharp">using System;
class MainClass
{
static void Main(string[] args)
{
int a,b,c,d,e,f;
a = 1;
b = a + 1;
b = b - 1;
c = 1; d = 2;
++c;
Console.WriteLine(c);
--d;
Console.WriteLine(d);

e = --c;
Console.WriteLine(e);
f = c--;
Console.WriteLine(f);
}
}</source>
<pre class=codeResult>2
1
1
1</pre>

==shortcut Operators==

<source lang="csharp">using System;
class MainClass
{
static void Main(string[] args)
{
int a, b, c, d, e;
a = 1;
a += 1;
Console.WriteLine(a);
b = a;
b -= 2;
Console.WriteLine(b);
c = b;
c *= 3;
Console.WriteLine(c);
d = 4;
d /= 2;
Console.WriteLine(d);
e = 23;
e %= 3;
Console.WriteLine(e);
}
}</source>
<pre class=codeResult>2
0
0
2
2</pre>
