下表列出了所有D語言支持的算術運算符。假設變量A=10和變量B=20，則：

運算符	描述	實例
+	增加了兩個操作數	A + B = 30
-	從第一中減去第二個操作數	A - B = -10
*	兩個操作數相乘	A * B = 200
/	通過取消分子分裂分子	B / A = 2
%	模運算符和其餘整數除法	B % A = 0
++	遞增運算符相加整數值1	A++ = 11
--	遞減運算符通過減少整數值1	A-- = 9

實例

試試下麵的例子就明白了所有的D編程語言的算術運算符：

import std.stdio;

int main(string[] args)
{
   int a = 21;
   int b = 10;
   int c ;

   c = a + b;
   writefln("Line 1 - Value of c is %d
", c );
   c = a - b;
   writefln("Line 2 - Value of c is %d
", c );
   c = a * b;
   writefln("Line 3 - Value of c is %d
", c );
   c = a / b;
   writefln("Line 4 - Value of c is %d
", c );
   c = a % b;
   writefln("Line 5 - Value of c is %d
", c );
   c = a++;
   writefln("Line 6 - Value of c is %d
", c );
   c = a--;
   writefln("Line 7 - Value of c is %d
", c );
   char[] buf;
   stdin.readln(buf);
   return 0;
}

當編譯並執行上麵的程序，它會產生以下結果：

Line 1 - Value of c is 31
Line 2 - Value of c is 11
Line 3 - Value of c is 210
Line 4 - Value of c is 2
Line 5 - Value of c is 1
Line 6 - Value of c is 21
Line 7 - Value of c is 22
