Because the minuses cancel themselves out,
For example,
-3 x -2 =6
3 x 2 = 6
When multiplying, the (-) doesn't mean anything. With maths, its not the why, its the how.
I have to disagree with something..in maths its not only about the how..the most important part of it is why..for example..you have 50 apples and want to give half of it to a friend..this might be a real life situation..in maths you would do it as 50/2...which would be a lot easier than sorting it out the hard way..so that's why you learn maths...to deal with situations in real life easier...the example above is a simple one...but more complex ones also come in to use. You just have to think about it, what is the use of learning all of this if it isn't going to help you when you finish school??!!
Negative times positive equals negative.
A minus plus a minus is not necessarily positive. A minus multiplied by a minus is. The reason being that the minus of a minus is a positive. It's a double negative.
negative 49. This is because a minus multiplied by a plus is a minus.
two negatives multiplied by each other would create a positive, since the two negatives cancel out each other
-- If they're being multiplied or divided, then they make a minus. -- If they're being added or subtracted, then they can make either a plus or a minus. It depends on which one is bigger.
