Sign Rule Scribe post #2 Patricia A.

The sign rules (short) 

When multiplying integers with the same value (+or-) (-2)x(-2) the product will always be positive. 

When the value of the integers of (+,-) (+2) x(-3) The product is always negative 

Sign rules cont'd 
(+4)x(-2)x(-1)=
       8 x (-1)=+8 
When you have even amount of (-) signs the product is Positive 

When there are an odd number of (-) signs the product is negative

  1. Good job explaining the rules, you should also add a picture to show how it works, maybe something like- (+2) x (+4) = +8
    (+2) x (- 4) = -8
    (- 2) x (+4) = -8
    (- 2) x (- 4) = +8
    Something like that so it's easier to understand your explanation, but good job!
