Yes Work can be positive or Negative.


No, this will not work. Postitive to Negative/Negative to Positive will work.


what is positive and negative


Positive to positive, and negative to negative outputs.


A Negative plus a positive = a negative because negative and a positive cannot work together Negative + Negative= Positive Positive + Positive = Positive when your dealing with numbers such as : -2 + 2 would equal a negative 4 -2 +-2 would equal a positive 4


There are different conventions as to what work is negative and what work is positive. The convention used by engineers and physicists is that work done BY the system on its surroundings is positive while work done ON the system by its surroundings is negative. Chemists reverse these conventions.


If work is done on the system then it has a negative sign. If work is done by the system then it has a positive sign.


Positive + Negative = Negative Negative + Negative = Positive Positive + Positive = Positive Negative + Positive = Negative


Negatives and Positives Positive + Positive = Positive Negative + Negative = Positive Negative + Positive = Negative Positive + Negative = Negative


A positive number times a positive number will always get you a positive number A negative number times a negative number will always get you a positive number (same signs will get you a positive number) but A positive number times a negative number will always get you a negative number or A negative number times a positive number will always get you a negative number (different signs will get you a negative number)




Yes. Negative/negative = positive Postive/Positive = positive Negative/Positive - negative


Negative * positive = negative Positive * positive = positive Negative * negative = positive


a multiple, as follows:positive * positive = positivepositive * negative = negativenegative * negative = positivemore than 2 numbers:positive * positive * positive = positivepositive * positive * negative = negativepositive * negative * negative = positivenegative * negative * negative = negativeand so on...also, (any number) * 0 = 0


A negative divided by a positive is negative. A negative divided by a negative is positive. A positive divided by a positive is positive. A positive divided by a negative is negative.


a negative x a negative= a positive, a positive x a positive= a positive, a negative x a positive= a negative, and a positive x a negative= a negative. Same thing with division. a negative divided by a negative= a positive, a positive divided by a positive= a positive, a negative divided by a positive= a negative, and a positive divided by a negative is a negative. U see?


positive and a positive is a positive negative and a negative is a positive to answer your question: positive and a negative is a negative.


it is negative. negative/negative = positive. negative/positive = negative




negative times negative = positive positive times positive = positive negative times positive = negative positive times negative = negative


The result will always be negative. Positive X Positive = Positive Negative X Negative = Positive Positive X Negative = Negative


positive 49 Because a negative times a negative is a positive. -7*-7=49. positive * positive = positive negative * negative= positive positive * negative = Negative


If you are subtracting the negative from the positive, the answer will be positive. If you are subtracting the positive from the negative, the answer will be negative.
