Here is one explanation. Suppose A and B are two positive numbers.
-A*0 = 0
(B-B) = 0, so substitutong this value in place of 0 gives: -A*(B-B) = 0
expanding the bracket, -A*B -A*(-B) = 0
Adding A*B to both sides, A*B - A*B = -A*(-B) = A*B
But A*B - A*B = 0, which leave -A*(-B) = A*B

What is a negative minus a negative?
A negative minus a negative turns the latter into a plus positive,for example -6 minus -3 would be :-6 ++ 3 = -3A minus negative always turns into a plus positive...To get more Specific:Suppose x and y are two POSITIVE numbers so that -x and -y are negative. Then a negative minus a negative = (-x) - (-y) = -x +yIf x > y the answer is negativeIf x = y the answer is zeroIf x < y the answer is positive
The real fourth roots of -16?
there are no real answers to an even root (2,4,6,8) of any negative number. the innovation of i allows you to find the unreal answers. i= the fourth root of positive 16 is 2. so, the roots of -16 are positive and negative 2i. post script: you cannot have a real even root of a negative because a negative multiplied by a negative turns into a positive.
Subtracting negative and positive numbers?
Basically if there is an even number of negatives, then it turns to positive, but if there is an odd number of negatives then it is a negative: 3-(-3) there are two minuses so it is even so it will turn positive: 3+3=6 Or with: 3+(-3) there is an odd minus amount (1) so it is minus 3-3=0 which can be seen all the time with 3-3 can actually be 3-(+3)
What does changing the value of a from a positive number to a negative number cause a parabola to do?
Assuming that a is the leading coefficient of the equation of the parabola, changing it from positive to negative will reflect the parabola along a horizontal line through its minimum - which will then become its maximum.
What added by what equals 29?
1 and 28. 2+27 3+26 4+25 and so on (even after the second numbers turns negative it continues.... forever...)

What element turns colors negative?
The dark side. The force turns colors positive.
When you have a positive and a negative it turns into a what?
That's going to depend on whether they're numbers, voltages, or personality traits. If they're numbers, it's also going to depend on which one is bigger, and on what mathematical operation you perform with them.
What is the absolute value of -4i?
4. i is just the imaginarY number used in an equatiOn, where there is a negative root (not possible to have a negative root) All yoU do is multiply the negative Root with a negative one, and you'll See your answer. absoluTe valUe turns any negative number into a Positive, even an Imaginary number. Do this and you'll be fine with your trigonometry!
Why is it when you add a positive number and a negative number it turns negative?
It does not always become negative , only if the negative number is greater then the positive number. Ex:-5 + 6 = 1 -6 + 5 = -1
What does a positive minus a negative equal to?
if a positive number minus a negative number, the minus turns to a plus sign. so its positive Ex. 2- -4= 2+4=6
What is charge of lightning?
the charge of a lightning is positive and negative. The positive is on the top of a lightning cloud and the negative is surrounded on the bottom. As it flashes down it is a negative. However, the ground is a positive charge so as it reaches down, it turns into a positive charge. I hope this will answer you question
