```\$a=2;
\$a=3;
...
print \$a.\$b   #string operator prints 2 plus the three or 23
print \$a*\$b   #arithmetic operator prints 6
print \$a x \$b #string operators prints \$a \$b times or 2 three times. i
+e 222
```
```\$a=3;
\$b="x";
...
\$a-=2;     #\$a=\$a-2; \$a is now equal to 3;
\$b x=3;    #\$b=\$b x \$3 \$b is now equal to "xxx";
\$b .="33"; #b=\$b."33"  \$b is now equal to "xxx33";
```
```\$a=1;
print \$a++; #prints a as one then adds 1 to it
print \$a;   #now \$a is 2
print ++\$a; #adds one to \$a and then prints its value which is now 3;
print \$a--; #prints 3 then subtracts one from \$a;
```
