Still remember the "Rules of Multiplying Signed Numbers"? Actually it consist of two types, the first type involves multiplying numbers with like signs and the other one involves multiplying numbers with unlike signs?

LIKE SIGNS
Rules: 
1.) When both factors to be multiplied are positive, the sign of the product is positive.
Example: 
567 x 7634 = 4,328,478
We don't need to put the positive sign because numbers with no sign are already considered as positive numbers.

2.) When both factors to be multiplied are negative, the sign of the product is still positive.
Example:
(-142) x (-120) = 17,040. 

Therefore: When we are multiplying numbers with like signs, their products are always POSITIVE.

UNLIKE SIGNS
Rules: 
1.) Positive multiplicand multiplied by a negative multiplier will result to a negative product.
Example:
(132) x (-13) = -1,716

2.) Negative multiplicand multiplied by a positive multiplier will still result to a negative product.
Example:
(-121) x (165) = -19,965

Remember: 


Multiplying numbers with like signs will result to a positive product while multiplying numbers with unlike signs will result to a negative product.
Anyway, the reason why I made this post is not to let you reminisce what you have ascertained in your Math subject way back in your elementary days because I know, this topic is so E.A.S.Y. Right?...Shame on you then, if you are educated then you don't know this. 

Nevertheless, the topic about "Rules of Multiplying Signed Numbers" somehow made me realize something. And I want to share this to all of you:
Simple but TRUE!
