A negative number. For example: -I -2 I = -2 because -2= 2 and the opposite of 2 is -2.
2 - (-4) is equal to 2 + 4. The answer to that is 6.
The additive opposite is +1/2. The multiplicative opposite is -2.
2
The answer is negative, no matter what.so.... if you had an equation like........-4/2=xx =-2Basically, if you can't think of what the answer would be, try it with the opposite sign. For example, -4/2=x could be turned into (x)(2) = -4. In this case, the negative is missing, so you would need to put it in. So if a negative number multiplied by a positive number is negative, the opposite must be true: A negative number divided by a positive number gives a negative answer.here is a song that will help with any complication with adding and subtracting negative numbers that my pre-algebra teacher taught me......(thanks Ms.Zachary!)Same sign add and keep,different sign subtract.Take the sign of the larger one,and then you'll be exact.
