The basic theory of imaginary numbers is that because (-) numbers squared are the same as (+) numbers squared there is not a correct continueos line on a graph.

I believe the parentheses eliminate the need for the negative sign. For example: negative $100,000 would be expressed $(100,000). Using the negative sign, it would read: -$100,000.
1). First, ignore the signs. Just go ahead and multiply or divide the numbers as if they were both positive.Then, when you have that answer . . .2). If both of the original numbers had the same sign, then the answer is positive.If the original numbers had different signs, then the answer is negative.
Negative numbers are numbers that go below.say you have 3 and take away 4 that would take you to negative 1 .
The rule is if a number is positive you add them. EX: 4+4=8 But if the numbers are both negative... you forget the plus sign and just put the numbers together and use whatever sign they have. EX: -4-4= -8 you see? you are adding them put if they are negative, they go down the number line. not up. Just picture a number line, if you add a negative number to an already negative number, wouldn't the number go to the left? The answer is yes. Yes it would. :)
Only if the absolute value of the positive number is higher.
