Signs of Products or Quotients of Signed Numbers
Very briefly, we state the familiar rule here:
(+) times (+) gives (+) 
(+) divided by (+) gives (+) 
(+) times () gives () 
(+) divided by () gives () 
() times (+) gives () 
() divided by (+) gives () 
() times () gives (+) 
() divided by () gives (+) 
So, when multiplying two numbers, or when dividing one number
by a second number,
the result is positive if both numbers have the same
sign
the result is negative if the two numbers have opposite
signs.
So, for example:
(+2) Ã— (+3) = +6
(+2) Ã— (3) = 6
(2) Ã— (+3) = 6
(2) Ã— (3) = +6
and
(+6) divided by (+2) gives +3
(+6) divided by (2) gives 3
(6) divided by (+2) gives 3
(6) divided by (2) gives +3
