* =	Multiplication	$ A * = B	$ A = $ a * B	Multiply the value on the right by the value on the left
/=	Division	$ A/= B	$ A = $ a/B	Divide the value on the right by the value on the left
. =	Connection character	$ A. = B	$ A = $ a. B	Add the character on the right to the left
%	Returns the remainder.	$ A % = B	$ A = $ a + % B	Returns the remainder of the left value pair to the right.
