Operator	Description	Example	Equivalent to	Significance
=	Assign value	$a =b	$a =b	Assign the value on the right to the left
+=	Add	$a +=b	$a = $a +b	Add the right value to the left
-=	Reducing	$a-=b	$a = $a-b	Reduce the value on the right to the left
*=	By	$a *=b	$a = $a *b	Multiply the value on the right by the left
/=	Except	$a/=b	$a = $a/b	Divide the value on the right by the left
.=	Connection character	$a. =b	$a = $a. b	Multibyte the right word to the left
%	Take the remainder	$a%=b	$a = $a +%b	Take the left side of the value to the right of the remainder
